Well, nevermind.  After writing this, I studied the log a bit more closely
and discovered that the 1280x1024 mode was unuseable due to insufficient
video memory.  Thus, it really *was* using 1024x768 resolution.  So, I
readded the manufacturers h/v values to XF86Config-4, rebooted the machine
and went into BIOS and increased video RAM.  Voila!  It works now in
1280x1024 resolution, which looks *alot* better.

Thanks, James
