This one (ThinkPad 750P) has 1MB video RAM, and maxed out at 640x480 
with 256 colors with the old Windows drivers. <calculating> But it 
should be able to do 24-bit color with that amount of RAM. Dang.

In any case, it currently has a grayscale screen, so 16 colors would do 
me just fine for the moment. I do have a TFT on a shelf, but I'd have to 
surrender the spiffy pen/tablet thing going on. More colors would be 
nice, but maybe later.

Now that I've gone off topic, a pointer to get Slackware 10.1/X.org 
v.whatever to use the plain ol' VGA generic driver would be most 
appreciated.

Many thanks,
