Can't help you with the ASM, but here's a C function that does the same:

#include <pc.h>

static void WaitVBlank(void)
{
   while (inp(0x3DA)&0x08);
   while (!(inp(0x3DA)&0x08));
}

the inp()'s are inline assembler macros, and optimize down to one opcode
apiece, so this function is pretty efficient.  You might want to compile
with the -S option, and check the assembler output to see the differences.

Later,
Matt.
