Subject: [9fans] self modifying code in intel vga bios?

Today, of course, we'd call this JIT, and shove it in a new page, and think
ourselves clever.
The last time I poked at one of these self-modifying bits they were really
just jitting a blit loop, in place. Drops register pressure a little bit,
which has always been a bit of an issue in x86 land.
