quadra 950 -> modprobe problems?

["R.A." <funkaster@mac.com>]

Ok, i've installed potato (or at least that's what I think...). I 
wen't through a network-base install with no problems.
After I boot into linux, I got a lot of errors like this:

modprobe: modprobe: Can't open dependencies file 
/lib/modules/2.2.20/modules.dep (no such file or directory)

and after setting the clock, the init stops...
any ideas?
regards,
ra.-
