Hi,

I just filed a PR on this, but thought I would send the code here
as well for some feedback.
Basically, my Netpliance I-Opener boots up and shows a graphical
logo while the BIOS does the POST and during the actual disk boot.
As a result, biosboot is loaded with the video still in graphics
mode.  This is ok for biosboot since it makes BIOS calls for output,
but as soon as it loads the kernel, all output stops.  It seems
like the kernel doesn't keep going,  but I'm not sure about this.

So I added a 'biosvideomode' function and call it just before
the 'print_banner' in biosboot.  This has the effect of switching
back to 80x25 and clearing the screen.  Combine this with printing
the text logo from Greywolf's .sig (hope you don't mind!) and it
looks pretty nice on my I-Opener.  And it will reboot cleanly without
manual intervention. (e.g. operator pressing TAB during boot)

Potentially wrapping the new stuff in a check for SUPPORT_SERIAL
might be appropriate to avoid calling a video function with no
video?  Or should biosvideomode() check for a video card signature?

Anyway, feedback, suggestions, complaints welcomed. :)
