AMD 760 support

[Scott McLeod]

Don't mean to step on anybody's toes but I spent my Friday learning what I 
could about how to get the gart to support the 761 northbridge
reading up on kernel coding style etc... I then patched against 2.4.9 and 
tested.  I would have posted this last night but to my dismay I've been 
unable to determine who the maintainer of the gart is.  Feel free to test 
this, and if you can point me in the right direction of the maintainer for 
this code I'd really appreciate it.  This patch also allows one to pass 
AGP_TRYUNSUPPORTED as a kernel param.

Thanks,
-Scott
