I decided to be adventurous and tried out your new kernel on my F8 x86_64 
system :p
The kernel boots OK, but once the system's started, the GUI has slowed 
down to an almost unusable rate. When I tried to start JACK in realtime I 
get this error message:
'cannot use real-time scheduling (FIFO at priority 10) [for thread 
-754224400, from thread -754224400] (1: Operation not permitted)'

Interestingly, when I tried to copy and paste the error message, QJackCtl 
produced this:
'QClipboard::setData: Cannot set X11 selection owner for PRIMARY'
'QClipboard::setData: Cannot set X11 selection owner for CLIPBOARD'

FWIW, the Fedora 7 rt kernel on the same architecture didn't have these 
problems on my machine - in fact it performed really rather well! :)
