I'm seeing basically the same thing with an RV280 on i386, I don't have a crash dump as it goes into a recursive panic but was able to capture a boot trace with a serial console. I was able to add a bit of debug before the call to bus_dmamap_load_raw() to confirm that the arguments looked correctly aligned. Is this by any chance on a machine with AGP? If so, I just checked in a change (ttm_agp_backend.c rev. 1.2) which may fix it. If not, can you tell me anything about the arguments to bus_dmamap_load_raw? Might also be helpful to print the fields of the ttm and bo objects involved in the call stack so I can see what state everything is in. I don't get this error with an RV710 on amd64, it boots fully but Xorg fails with an error from somewhere in ttm/uvm. What's the error? Do you have dmesg output or Xorg.0.log?
