Try compiling SCSI as modules instead -- that's what I've got here, and it
works (Tekram controller plus two drives).
Mkinitrd looks for the SCSI modules to put into the initial RAM disk
image, so you'll need them.

Sounds like the SCSI stuff isn't being loaded.

Hmmm... the i850 works for me.

No, that's the correct one -- I used it here.

This I'm not so sure about. If you read the README file for the kernel
sources, it says:
If you ever need to change the default root device, video mode,
ramdisk size, etc. in the kernel image, use the 'rdev' program (or
alternatively the LILO boot options when appropriate). No need to
recompile the kernel to change these parameters.
Also, the Documentation/ramdisk.txt appears to say that you can change the
size, without recompiling.
