This card is *NOT* an ATI produced card. Any cards not made by
ATI, may or may not work at all with XFree86. If a board vendor
who has licenced ATI's technology makes the board work *exactly*
like ATI's own hardware, then it should work. If they change the
design, then it may or may not work. I do not have any non ATI
boards using ATI chips.
I have had various reports from people that they could not get
Radeon 7500 and other cards working without tweaking things. All
cases so far, their hardware was not ATI boards.
In order for this hardware to be supported properly in XFree86,
and in Red Hat Linux, someone who has the hardware, needs to
experiment with config file settings, and then file a Request for
Enhancement bug report in bugzilla, including their config file,
X server log, "lspci -v" and "lspci -vn" output, and preferably
the exact board manufacturer's name, and the marketing name the
board is marketed as, ie: Radeon 7500 whizbang 2000
By using the Subvendor and Subdevice ID's, I can add new entries
for that specific card to the database and tweak the
configurations.
Without end-users doing this troubleshooting however, there is no
way to support this hardware without someone sending me a board.

Again, once you get it working, please file an RFE with the
details above, and I'll try to get it added to the hardware
databases.
