Virt Console text screen resolution problems and setting it

[Hanasaki JiJi <hanasaki@hanaden.com>]

I have lilo setup to boot into a high resolution vga screen resolution. 
   It comes up fine; however, somewhere in the middle of the boot 
process, maybe when teh framebuffer drivers are loaded, it switches back 
to a lower resolution - standard res?

1. what would cause this?
2. how can it be prevented?  and if not prevented, what command line 
program, with what options, will set the text resolution high again.

Running Woody.

Thank you.
