Hi Wolfgang,

I was banging my head against the wall with the same issue, but after a *long* 
Google search, I found that disabling acpi did the trick for me.

For a tutorial I wrote on the subject, go to
http://www.akjmusic.com/linuxaudio.html

Basically, like it says, the most critical thing was shutting off acpi with an 
	
	append "acpi=off"

in the lilo.conf file, and rerunning lilo and rebooting....

BTW, I tend to still get xruns with '-p 64 -n 2'. I do sr=44100, -p 128 -n 2, 
and never have a problem for hours on end.
