	Hi;

	Well, Ive been running an athlon x2 system in native 64 bit
for the better part of a year now, with no problems. The 32 bit
libraries even make 32 bit programs I compiled 9 years ago just
work. Even the proprietary ATI fglrx driver works fine. (well, much
like flash, your definition of 'fine' may vary...)
	Not sure if there are any real advantages to you with a
64 bit userspace with your workload . Some people like to run a
64 bit kernel with a 32 bit userspace if they have a lot of
memory. But I personally havent noticed any downsides to running
amd64 native, unless you want to complain about disk space used
by 32 bit libraries and what I suspect are generally larger
64 bit binaries.

ps. for the sake of completeness, this is a Foxconn A7DA-S mb, with
an athlon-x2 5050e, an onboard ati radeon hd3300 with sideport memory,
and 4gig of ram.
