Mandrake - the PPC version to be precise. I thought you had mentioned a
certain aversion to it, but I won't take it personally. ;^)

I made it, based on info I picked up along the way.  For the Mandrake RPM,
it's only applied when %ifarch ppc.  That's all I change.

Could have been hardware.  I had a 7600 donated, and it worked intially
with MacOS and LinuxPPC installed, but then started flaking out (perahps
shipping damage, who knows?). Once I repartitioned/reformatted and
re-installed (Mandrake of course) it's been OK.

On PPC, using kernel.org sources, generally every 2nd or 3rd version
release can have some particularly bad problems on PPC.  Most PPC folks
will use Ben Herrenschmidt's kernel of the BK tree, but I'm kind of locked
into adapting the Mandrake kernel for PPC.
