Lombard hard freeze (update: mem>64MB)

[Seanano]

  I've been running a lombard with 192 megs of RAM since it was purchased
without any problem.  I've been running kernels 2.2.14 - 2.2.15-pre20
with almost all of the 2.2.15-preXX kernels coming from the rysnc server
at linuxcare.com.au.  Up until I installed the 9.0.4 upgrade a few weeks
ago I was using bootX, now I've switched over to yaboot.  I usually
compile multiple programs at a time and I've never seen any kernel errors
or freezes.  When the kernel boots it shows Total Memory = 192MB.

  I'd be happy to run some tests if needed.  My network access on the
lombard is a bit unstable right now so I couldn't download the gnomehack
source...  I should be back to normal in a few days.  I don't even have
gnome installed anyway...
