>Hi everybody!
I’m writing this post directly from my brand new Asus Eeepc 1215p, just to let you know it’s working fine :)
I’ve installed Debian GNU/Linux 6.0 squeeze daily build (net install, non-gtk installer) from a USB stick, and now almost everything is at its place.

IMPORTANT NOTES
You need the daily build image, otherwise the atl1c driver wont recognize the Ethernet card (and with a netinst image, you NEED the Ethernet card).
You won’t be able to use the wireless card unless you add the non-free repository to /etc/apt/sources.list and install the firmware-brcm80211 package.
There’s quite an issue with the audio: with default setting speakers and headphones work good, but the microphone doesn’t; if you add to /etc/modprobe.d/alsa-base.conf the line

options snd-hda-intel model=basic

the microphone will work, but the headphones won’t; I still don’t know how to fix this, but given that I rarely use the microphone, I’ll use default setting most of the time.
UPDATE 1: I updated the alsa driver to 1.0.23; now adding to /etc/modprobe.d/alsa-base.conf the line

options snd-hda-intel model=auto

audio is perfect: inserting the headphones jack mutes the speakers, and the microphone is working.

with alsa 1.0.21 alsamixer said my audio chip was Realtek ALC269, now with 1.0.23 it has become Realtek ALC259 (mumble)

Something is rotten in the state of Ethernet: after an hour or so it stops working :(. Nothing is written in dmesg, and I don’t know where else to check; it’s really strange, because I can use the wireless card for 5 hours nonstop (WPA encryption) without problems, but not the ethernet: this must be investigated.
UPDATE 1: removing and re-adding the atl1c module (the ethernet card driver) the card comes back to life, dunno if it’s a definitive solution.
