Hi,
Just got a chance to try the latest CVS code, I noticed above patch is in
the CVS. However, this patch breaks the DELL VE card detection (at least on
my DELL's card). The subsystem vender ID of my DELL VE card is 0x1002 (ATI's
ID) and the bit 12 of subsystem card ID is reserved for DELL. It appears
some OEMs do not follow this rule. In my next patch, if no other issue, I'll
change it to test ATI's ID instead of DELL's ID.

Hui
