  I'm writing a program that's going to need access to SVGA modes and I've
got a few questions.  The docs say that DJGPP can handle any SVGA mode it
has a driver for as long as it's 256-color.  What would I need to do to
use HighColor or TrueColor?  Do I have to write it all from scratch or
will DJGPP still be able to give me a linear pixel frame at 0xD000000?
  Second question is the one that everybody got bored with a long time
ago.  I want to release this as a mix 'tween freeware and shareware -
freeware that accepts donations.  So far, everything except the
_go32_dpmi* functions isn't FSF code - if I use the DJGPP standard
graphics interface does that put me under any special restrictions?  I
don't think it will since I'll probably release the source too, but I'm
just checking before I get any time invested in those graphics drivers. 
  Third question is has anybody done this before?  I don't relish 
writing drivers for several SVGA modes and I'd love to mooch them off 
someone else.  Maybe I could use Windows drivers?  Are there any other 
standards for this kind of thing?
  Fourth question belongs in a separate post.
  And now you get a lollipop for having read this while thing. :)
