Doesn't sound good - cmd+v should be passed to the kernel, which would be the very first thing that gets loaded... if it's not even doing that...
Try boot hd: or mac-boot from the open firmware prompt.

I managed to get into Open Firmware. Wheee!

With 'boot hd:' I get the following message:

"MAC-PARTS: LOAD (noninterposed) not supported-size=0 adler32=1

LOAD-SIZE is too small"

With 'mac-boot' it resumes the boot process with the same results as before.
