Does serial console work without VGA cards?

[Jam]

Hi,

I've installed RedHat Linux 9 and found it is using
GRUB-0.93-4 as its boot loader.  I want to use serial
console, so configured grub.conf to specify "serial --unit=0
--speed=9600" and "terminal --dumb serial".

This works fine if I leave VGA card in the system.  However,
if I took VGA card out, GRUB won't run.  System stuck when
GRUB tried to show something.  For example, if I specify
timeout, GRUB shows press any key message for a while
through serial line, then stuck.

Is this problem already solved in the current version?  If
not, please fix this problem.  Thank you.
