I know your pain so well!  I have a r200 on a nforce2 board.  I have the 
same problems as you.

1.It looks as if your pci id is wrong.  I might be wrong, but I see  
3:0:1 and 3:0:0.  You should not use the BusID option if you can avoid 
it.  There is a free pci scan with every startx!  The point of the scan 
is not having to set the id.

drm0 at pci2:0:0:  class=0x030000 card=0x7149174b chip=0x514c1002 rev=0x00 
    vendor   = 'ATI Technologies Inc.'
    device   = 'R200 Radeon 8500 / 8500LE'
    class    = display
    subclass = VGA

You see here on mine I am getting a driver attached to my card.  The 
_none_10 at pci3:0:1 means there is no driver attacked, or at least drm is 
not working. 

2.You must preload agp.  The handbook clearly states you have to have 
agp in the kernel or preloaded.  You should not kldload or kldunload agp.


This is just a sample of my /boot/loader.conf file.  You see I have the 
radeon and agp drivers preloaded.

3.The current version of dri in the kernel is outdated and does not have 
accellerated drivers that work.  I think they will be updated after the 
release of 5.3 when the new xorg sever is put into ports.  You can use 
dri without x, but no one does.  Dri is its own project and a part of x, 
but in FreeBSD dri is part of the base system since it has drivers(I 
think this is why).  So this means no loading dri modules in the 
xorg.conf file, and no hardware accellerated 3d for you until the 
update.  Before you mention it, I do know you have the RV280 and not the 
R200 like me.  The RV280 is a modifed R200 and does use the same driver.

I also noticed you have 2 radeons in the pciscan.  I have a tripple head 
8500(svideo, vga, dvi) and I only have 1 radeon show up.  Do you have 2 
cards(it looks like 1 card, could this be a dual head side effect? could 
I get a dmesg on this)?  What settings have you changed to get this to 
happen or is it deafult?

Finally, if you do all I said you should have a working x and system.  
Right now I can get 25-30 fps in glxgears fullscreen.  When the new 
drivers are here that number should be more like 2500-3000(or was there 
another zero?).  If you need any files just email me.
