i'm using the above card with a new install of freebsd 7.0. when i ran Xorg -configure the driver came back as "vesa". however after a couple of crashes, i suspect that it may not be good to leave it this way. i loaded the (ati) wrapper and got this: 
xauth:  creating new authority file /root/.serverauth.1474 
xauth: (argv):1:  bad display name "" in "list" command 
xauth: (stdin):1:  bad display name "" in "add" command

now this is my first video card... and after reading the manpage for "radeon" the only thing which might help is: 
       The driver auto-detects all device information necessary to  initialize 
       the  card.   However, if you have problems with auto-detection, you can 
           VideoRam - in kilobytes 
           MemBase  - physical address of the linear framebuffer 
           IOBase   - physical address of the MMIO registers 
           ChipID   - PCI DEVICE ID 
okay, maybe i could write in the relevant info in xorg.conf, but other than VideoRam, i wouldn't know where to start. and i'm not even sure if the bloody card is supported since i didn't see it on the manpage... any help at all that's pertinent would be appreciated. thanks in advance.
