[PATCH] AGP: Try unsupported AGP chipsets on x86-64 by default

So far all new ones have worked and there isn't much variation because
the CPU does all the interesting bits.

So enable try unsupported by default.

Can be still disabled with try_unsupported=0 (module) or
amd64.try_unsupported=0   (boot option)
