Hey folks --
My goal is to nuke vesafb, and replace it with genfb in the i386 and amd64
kernels. This is a prereq to having proper splash screen support. I would
like to check in the following changes to the x86 bootloader and kernel. Any
objections?

With the above changes and the proper options in your kernel config, you can
select a framebuffer mode in the bootloader by doing 'vesa modenum', so a
boot.cfg entry would look like this for eg. 640x480x8:
menu=Boot NetBSD:vesa 0x101;boot netbsd
Where do these 0x101 and similar numbers come from? Linux also uses
them (dunno if with the same format) and I always found them very
confusing. Couldn't we just give a string such as 640x480x8 and parse
it? (where parsing could simply be a mapping table from known valid
strings to numbers)
