	Dont know what the kernel would do, but you might try changing the
OSC1 oscillator can (near the Brooktree RAMDAC) on the PMAGB-B to about
108 MHZ (its probably 119 MHz now). All the PMAGB-Bs that I have seem to
have that oscillator can in a socket. You also have to install the jumper
that selects OSC1. If you do this you will get 1280x1024 with about 60HZ
refresh (as long as the kernel doesnt change anything). 
	BTW several HP fixed freq monitors work with PMAGXXX video cards
(A1097, A2094A for example work at 1280x1024, 72Hz refresh)
	I'll give you a VRT19 here in the SF bay area if you want to pick
it up... (I dont want to pick it up, move it, roll it, send it, shove it,
or push it. Just too damn heavy...)
