Sorry it took so long to get back to you; I needed to buy a new mouse, and it just came today.

Yes, I tried the default kernels from Sarge. The guy who helped me set up Sarge had
configured BootX
to boot from a ramdisk/kernel on the Mac OS partition and gave BootX an optional parameter
for root's
]\parition; I have no idea if this is standard. I know Yellow Dog 3.x had you configure BootX to
load the kernel on root's parition.

The monitor has the power light begin flashing, so I don't think that the problem is waiting for
to start; I think the kernel isn't loading.

I was really hoping ot hear from one of the people who assured me they had used Sonnet
cards with Debian; if you're out there (John Schmidt, Peter Rooney, Ralf Saalmüller), please
give a shout-out.
