[ale] Low-Res X Problem

[Steve Throckmorton]

I am pretty much a Linux newbie, but your problem interested me, so I poked around on some X sites, and  this  one says that ISA chipsets must be correctly specified in the device section (not necessary for PCI).  I have no idea if this helps or not, but thought I'd pass it along.
