One more update on my driver problem.

It turns out that the problem goes away if I restart my machine with  
the restart button.  NEXTSTEP must be doing something to the card  
that prevents it from going into 640 x 480 ; 8 bits per-pixel mode,  
at least with the initialization in the built-in VESA driver, the  
vesa_s3 driver, and a couple of VESA testers I tried from the net.

So as long as I do a hard-restart, or never start NEXTSTEP, the demo  
version of Executor with color mods in it starts OK with the built in  
VESA driver.  It does have a few glitches, and is still in the  
embryonic stage w.r.t. color, but it's cool to see Lemmings for the  
Mac start up in color.  However, if I try to use the vesa_s3 driver  
that Csaba and Matin Oldfield suggested, Executor dies with an  
illegal instruction error down in a memory location that the go32  
debugger reveals to be the legitimate starting address of one of our  
routines, so there's some sort of smashage.  The smashage is quite  
possibly due to our funky memory layout, since we start our text  
segment at location 0.  This hasn't hurt us so far, but we're looking  
into it.

The quick response that I've gotten to this question has been very  
handy.  Thanks.

The GRX 1.03 "vesa_s3" grn driver should support your card in 256  
color
acclerated modes. Also, the GO32 1.11 built-in driver may support it
using 256 colors and non-accelerated VGA-style memory access.
