Yes, and I can't even get it to do 8bit 256 color 640x480.

It's a Toshiba Satellite Pro 410CDT.  Linux for Laptops has no "Satellite
Pro" links but it does have a "Satellite 410CDT" link.  According to this
link, the LCD monitor worked under XFree86 3.3.6 using:

Horiz: 20-64
Vert: 40-90

Chipset: CT 65548 (the Linux for Laptops entry lists it as 65545, but
Toshiba's spec sheet for this particular laptop states that the chipset
is 65548).

Read up some more on this monitor.  Apparently X only can see two dot
clocks when running the laptop using just the LCD: 25.2 and 28.3.  If you
add an external monitor a third dot clock is visible: 40.

All the XF86Config files I've seen for this laptop use the 28.3 dot
clock.  What resolutions can the 25.2 dot clock support?
