The issue is that GL_TOTAL_PHYSICAL_MEMORY was added a bit after the other 4 
query flags, Sunny says they're working on adding it to the spec. So there is 
a range of fglrx version that supports ATI_meminfo, but returns zero on 
GL_TOTAL_PHYSICAL_MEMORY_ATI. So if we want to use this as-is we have to take 
care that we don't set the vidmem to zero accidentally.

Another extension is a possible way to go, but there are still r300 to r500 
chips where the driver has been discontinued and where the vidmem info is 
useful too. These cards most likely won't get the new extension in that case.

@AMD: The discontinuing of fglrx for r300-r500 chips is really a pain for us. 
There's essentially no way to use those cards on Linux right now. The Open 
Source driver that ships with current distros can't even run 3DMark 2000 
properly, and the 9.3 driver doesn't run on up to date distros. Currently I 
have to tell everyone who has such a card that it probably won't be useable 
for probably another year :-(
