Unfortunately there are other BIOS vendors, and we need a solution that works
across the board and doesn't trigger false positives. (Most BIOS's don't set
the enhanced keyboard bit for USB keyboards, and some don't set it for PS/2
keyboards either, hence turning off -P.)

Not all of those machines have TGA's, and you could be testing out the TGA
driver. However, there is no song and dance, you set the console to serial for
a TGA machine and it all works and fine. Not exactly a song and dance. :)
