On HP nx6325:
1) The audio is back (thanks for reverting x86_64-mm-cpa-einval.patch)
2) CPU hotplug is busted (onlining of CPU1 kills the kernel), probably due to
the same issue that I'm having with the -hrt version of 2.6.23-rc8 (we're
debugging it right now)
3) Some call traces unrelated to 2) appear in dmesg:
a) This probably is due to the fact that I've compiled two RTC drivers, by
mistake ;-)
Duplicate file names "rtc" detected.

b) I have no idea what causes these to appear, but the networking works
nevertheless:
