Built and modprobed : no performance difference. Both modules have the
same version tag : 1.1.1 20010405
version : file size / modprobed size
kernel : 123.238 / 89.848 bytes
X : 121.896 / 88.824 bytes
, so the two seem to be somehow different.
Test results :
(A21p = PIII-750, Mobility-128 16MB , RH XFree86-4.1.0-6)
(A30p = PIII-1200, Mobility-Radeon 32MB , XFree86 CVS 20011127)

As a sidenote, I observed following anomalies :
1. sometimes, starting X leaves me with a black screen ; I have to
switch the LCD-panel off and on again (through the keyboard Fn
powersaving key combination) to view the X display ;
2. switching between console and X gives me a flashing display when moving the mouse,
again resolved by temporarily switching LCD off/on ;
3. trying to observe 3D performance by means of RTCW MultiPlayer test
0.9.20 : RTCW does not switch to full-screen when told to do so, and
hangs when the MP level is loaded. Cannot return to X or console, and
have to remotely (ssh) restart the machine.
As the Radeon Mobility seems to be quickly becoming mainstream for mid-
and high-range portables, I'd be happy to provide further extensive
feedback.
Kind regards,
Didier
