I've been running RedHat 5.2 on a 386 SX-20 w/ 16 megs of ram and an embedded Chips & Tech 82c450 video board w/ 512k of RAM. Under the stock Xfree86 RPMS as distributed with the 5.2 CD, SuperProbe was able to identify the graphics chipset and from that I was able to get an X configuration working. After the update, SuperProbe cannot correctly idenfity my Video Card and reports; First video: Super-VGA Chipset: Chips & Tech (chipset unknown) (Port Probed) Signature data: 43 (please report) Memory: 0 Kbytes RAMDAC: Generic 8-bit pseudo-color DAC (with 6-bit wide lookup tables (or in 6-bit mode))
We will need to get card with this chipset in to accurately test this bug. Until then you can submit bug information to www.xfree86.org and downgrade to the older version until they can come up with a fix.
