This is a well known problem, with radeon cards on machines with Via
chipsets. The freeze occurs under FreeBSD, Linux and even Windows,
most easily with DRI but sometimes without DRI. The only solution i have
found is to exchange the video card on the machine with a Via chipset to
an nVidia card, and put the Radeon on a machine with an Intel chipset.
Now i have zero problem, including with DRI. The radeon card now drives
a beautiful 1920x1200 screen without any problem, and gives a very good
display quality.
