ATI Radeon 7500 & Woody - Unknown Chipset (0x5157)

[Kenneth Jacker <khj@be.cs.appstate.edu>]

I am running 'woody' with the 4.1.0-16woody1 version of XFree86 on a
fairly new Dell with a "ATI Radeon RV200 QW [Radeon 7500]" video 
controller.

For some reason, the board isn't being recognized when I 'startx'.
In particular, this:

    (II) ATI unknown chipset (0x5157)

and this:

    (WW) ATI: PCI/AGP Mach64 in slot 1:0:0 could not be detected

show up in the XFree86 log.  My screen finally returns to "text mode"
with a message something like, "No device found".

Doing some investigation, it appears that the video device *is*
supported under 4.1.0 as shown at:

    http://www.xfree86.org/4.1.0/Status6.html#6

and

    http://www.linuxforum.com/linux-hardware/video.html


Though I couldn't find a driver that looked useful using 'modconf', I
manually 'modprobe'd

        /lib/modules/2.4.18-bf2.4/kernel/drivers/char/drm/radeon.o

but it still produced the same behavior.


Any help/ideas/suggestions will be *most* appreciated.
