No, it's a desktop Celeron 900.

I did retest things more toroughly today after I booted up 2.6.3-rc2. I focused on testing KDE login since this is known to break. Startup scripts (discover) loaded also i810_audio, I unloaded it.
Plain bootup gave PCI: Setting latency timer of device 0000:00:1f.5 to 64 intel8x0_measure_ac97_clock: measured 49671 usecs intel8x0: clocking to 41136
and it did not work. Unloading and reloading snd-intel8x0 gave PCI: Setting latency timer of device 0000:00:1f.5 to 64 intel8x0_measure_ac97_clock: measured 49281 usecs intel8x0: clocking to 41139
and it still did not work (way too fast, probably even more than twice). Now I tried modprobe snd-intel8x0 ac97_clock=41140 It loads silently but still does not work.
Now I started to suspect that loading i810_audio might screw things up. Removed the module and rebooted, no i810_audio loaded, still the same.
Reproduced the problem with mplayer too. It depends on the input file bitrate!
mplayer /usr/share/sounds/KDE_Startup.wav gives the same very fast sound since it's a 22 KHz mono sample.
mplayer -srate 48000 /usr/share/sounds/KDE_Startup.wav works fine. Same applies to all files.
So maybe it's a userspace resampling issue? I see that the hardware talks 44 KHz.
