"Fixed frequency" is not a problem and pretty much any video card
can nail the frequencies if you've got the correct modeline. The
problem is that most fixed frequency monitors are also "sync-on-green"
or in the case of Sun, "composite-sync". NVIDIA cards cannot do
sync-on-green nor composite-sync.

That's correct for the bios screen, but svgatext mode should be able
to let you see most of the boot messages (from the part where it gets
loaded).
