Install -

The install process went quite smoothly, only problem is that i found impossible to install double-booting with existing Windows XP Home installation, because every attempt to resize windows partitions ended up with errors and at the end i lost everything, wiped up the disk and re-partition from scratch. Once decided i had to give up dual-booting everything was ok: i made a 30 Gb root partition, a 40 Gb home partition and a swap partition. Make sure to make a swap partition larger than installed ram memory, otherwise you won't be able to put your laptop on sleep state.

What works -

CPU - (perfectly) - Once booted in your freshly installed system you'll be running a generic 686 kernel, first of all make sure to install a new SMP kernel package, and you'll be running a wonderful dual-core enabled system
Ethernet - (perfectly) - Out of the box, as expected
Wireless - (perfectly) - Out of the box as well, detected as eth1. After a while you might be tempted to use NetworkManager, it's worth, but make sure to comment out previously configured net interfaces in /etc/network/interfaces (to get managed by Network Manager properly you must have something like this:
auto eth0
auto eth1
Graphic - (perfectly, needs tweaking) - When first booted you will probably have a wrongly configured 1024x768 xorg display, due to well known problem with intel chipset. just install 915resolution from universe (or multiverse? don't remember) and you will automatically be given the right 1280x800 widescreen resolution. AIGLX with compiz works as well, but under it there are some problems with applications using GL, as googleearth or blender
Keyboard, Touchpad - (perfectly) - seems to work quite well out of the box.
USB - (perfectly) - tested several devices, seems ok.
Audio - (quite well) - recognized out of the box, works well with alsa for normal audio tasks, but there are some quite annoying problems with jackd, qsynth and midi programs: a lot of xrun i couldn't get rid of and a very noisy resulting sound. Didn't find a solution yet. integrated loudspeakers are nice, but maximum reacheable volume is quite low anyway.
suspend-to-disk and sleep - (quite well) Hybernate and sleep work very well, machine get suspended and waken almost perfectly. a minor problem is that after a resume from sleep one of thegnome-applets i have on toolbar for monitoring cpus's frequency get stuck at maximum speed (usually processor number 1), I haven't tried yet if it's just a frozen applet or the processor's speed-step doesn't work well after resume.
Infrared remote - (quite well, needs tweaking) - dv5175ea comes with an integrated infrared remote control, really very nice and useful for presentations. It works well out of the box, it repeats some keyboard's key. Only problem i had it was a double echo of key-pressing that produced for example the skip of two pages at the same time in presentations or Acrobat Reader. I solved it tweaking the delay of key repetition in gnome system » preferences » keyboard settings.

Doesn't work -

Integrated media-card reader - It's a Texas Instruments device, known for not working under linux. I think a driver is under development, but i was not able to compile it: i had an error i couldn't fix.

Not tested (yet) -

Firewire (should work)
pcmcia (should work)
DVD burner (should work, works well as reader, i've tested it)
