   So my question boils down to this: what is the cleanest way of
   accessing an absolute address such as 0xa0000 in Quick C?


I don't use Quick C, but I can tell you what works for me in Turbo C. 

PutPixel (int x, int y, unsigned char c)
{
  unsigned char huge *w;		/* huge seems to work better here */

  w = (unsigned char huge *)(0xA0000000L + (long)y * 320L + (long)x);

  *w = c;
}


Good luck...
