I didn't have to put any real effort in on my PC (RH8, ide, athlon),
I just installed a patched kernel from Planet CCRMA and rebooted.

I get xruns at 64 samples/period (and 128 with heavy disk load), but I
think that's a problem with the ext3 filesystem - others have reported this
too. I'm happy at 256 so I haven't bothered remounting the partition to
find out.

JACK/no JACK makes no noticable difference to the xruns.
