[ltp] External Video on T30

[Michael B Allen]

Hi,

I've been stuggling to get the dsub out on the t30 to give me anything but
640x480. I need it to 1600x1200 for it to look even sane on the flatpanel
display I have (DVI doesn't work). Does anyone have the external video
working on the t30? This works under Win2K although it looks pretty
bad. Here are lines that looked insteresting from the log:

Here's what I thought would have worked (simplified for breivity):

        Subsection "Display"

                Modes       "1600x1200"
        EndSubsection

EndSection

I'm willing to get my hands dirty for this. Where does this radeon driver
come from exactly?
