2.x mimics the firmware output, -current uses all it can get, at least
with the onboard video.

What kind of video hardware are you using? Onboard? Creator? Something
else? In 2.x most things are unaccelerated, this changed in -current and
3.0

Depends what you have, there are many variants of the U5/U10 mainboard
and they come with two different video controllers - older ones with a
Rage II and 2MB VRAM, newer ones have a Rage Pro and 4MB VRAM. I have
the latter and I'm running X in 1152x900 at 24bit, for viewing webpages
the video controller is certainly not the limit.
Creator / ffb cards can display higher resolutions in 24 bit, so it
really depends on which mainboard you have and what resolution you want.
X11 support in 2.x is rather limited but 3.0 will have (more or less)
full support for the most common chipsets.=20
dmesg output for the Rage Pro looks like this:

machfb0 at pci1 dev 2 function 0: ATI Technologies 3D Rage Pro (rev.
0x5c)=20
machfb0: 16 MB aperture at 0xe1000000, 4 KB registers at 0xe2000000
memctl: 00651a77=20
machfb0: 4096 KB SGRAM 98.924 MHz, maximum RAMDAC clock 230 MHz=20
machfb0: initial resolution 1280x1024 at 8 bpp

( with a -current kernel. 2.x should be slightly different )

You can probably use the flatscreen with the onboard video ( it should
default to 1280x1024 in 8bit, ~70Hz ) or with the Creator if you get an
adaptor somewhere.

have fun
