Printing radeon total memory

[Julian Coleman <jdc%coris.org.uk@localhost>]

Hi,

I have an XVR-300 in my U45, and the attach line implies that it has 64MB
of memory.  This confused me, as I was fairly sure that the card had 128MB.

How about this change, so that we print the total memory if it's more than
64MB?  With it, I see:

  [   1.0000000] radeonfb0: 128 MB, 64 MB aperture at 0x10000000, 64 KB registers at 0x00100000

Regards,

Julian
