Thanks Srinivas.  I upped it to 32m, but then

drm0: <ATI Radeon HD 3200 Graphics> on vgapci0
vgapci0: child drm0 requested pci_enable_busmaster
info: [drm] Initialized radeon 1.31.0 20080613
contigmalloc_map: failed size 33554432 low=0 high=ffffffff align=4096
boundary=0 flags=00000102

So then I upped it to 64m.


rm0: <ATI Radeon HD 3200 Graphics> on vgapci0
vgapci0: child drm0 requested pci_enable_busmaster
info: [drm] Initialized radeon 1.31.0 20080613
info: [drm] Setting GART location based on new memory map
info: [drm] Loading RS780/RS880 Microcode
info: [drm] Resetting GPU
info: [drm] writeback test succeeded in 1 usecs

And now window dragging is very smooth.  X also starts up faster.  Thanks a
lot.

Neil.

Some AMD (ATI) graphics cards seem to require a 32MB physmem region<br>
for DRI to work.<br>
In /boot/loader.conf, set vm.dma_reserved to 32MB. Should work well!<br>
<br>
Good luck,<br>
