I'm in the process of adding DragonFlyBSD support to the BSD kernel
module which seems to be going pretty well except ...

        When I load the drm and radeon modules (I have a 9200SE on my box)
and start up X (Xorg 7.2.0) I see a series of calls to drmAddMap finishing
with the message "added 8192 byte SAREA at 0xdf7c2000" then a call to
drmMap which fails because dma->pagelist is NULL because drmAddBufs has
never been called. The thing I can't see is how drmAddBufs is supposed to
be called and with what parameters, or indeed if it should happen at a
lower level inside the kernel module or as part of the open code perhaps.
Could someone shed some light on this for me please.

        Once I get it all going I'll raise the question of what to do with
my DragonFlyBSD patches.
