Damn, I wish I would have just done that right from the beginning...
Turns out SVGAlib does all of the vm86 stuff through a file called
lrmi.c. So I looked in lrmi.c and at the top is this comment about how
it's the "Linux Real Mode Interface" and some other stuff that makes it
sound an awful lot like public domain.
So I went and found the "Linux Real Mode Interface" and downloaded it.
It's just a few C files along with a makefile to make a little test
program. It looks pretty nice, at least the test program compiled without
warnings and didn't require me to install any libraries, and as an added
surprise, worked without a problem. (looks like all the test program does
is let you pick a VESA mode, then it sets it for five seconds, then
restores the old mode, but that's enough to say that it works)
Since it's mostly compatible with public domain, I don't even have to try
to figure out how it works, I can just use it. I'm not sure if the test
program does VBE 1.2 or not, but I'm sure I can figure that out on my own.
I'd still like to know how that vm86 call works, but this should work just
fine for what I'm doing.
It's so nice to be in Linux again... Copy and paste doesn't work in
Windows. (At least not with the middle mouse button, which is how I
usually do it.)
Interestingly, I've learned that there're 357 people signed up to this
mailing list. I had no idea. I thought it was more like 20 or 30.
