I had a similar freezing on several FreeBSD 8.0 boxes with either 
'radeon' or 'radeonhd/radeonhd-devel' with recent ports. With more 
expensive graphics cards, like HD4830, HD4850 we never had the issue, 
but with smaller cards, like HD4670. HD4670 never worked. HD4770 cards 
work with explicit set

option "DRI" "OFF"

As far as I know,  WITHOUT_NOUVEAU does have no effect on the current 
ports, since it is reported in ports/UPDATING, it prevents building 
nouveau driver which is broken when using newer libdrm/dri and libGLUT, 
but those new ports do not seem to be merged into the tree.

The situation is heavily unsatisfying, since one need an expensive 
AMD/ATi Radeon card to gain non-3D poor functionality, where a cheaper 
one should be do the same - but the cheaper ones don't work. Even if one 
uses AMD64, the situattion is worse and I have no reason using 
Linux-driver on a FreeBSD box. Hope the situation gets cleared in the 
nearest future. It's a kind of deadlock. As I said, either spenig a lot 
of money for a working RV770 based AMD graphics card with poor 
functionality or nothing so far, since most smaller RV730 chips aren't 
supported properly by the most recent drivers.
