Unfortunately no, I can't.  After cloning and building the radeontool tree, the
avivotool program won't run with either UMS or KMS.  When executed as root, it
hard-locks the machine.  When run as a user, it segfaults like so:

(gdb) run regs all
Starting program: /usr/local/src/radeontool/avivotool regs all
mapping ctrl region

Program received signal SIGSEGV, Segmentation fault.

1619        ctrl_mem = avivo_device->regions[ctrl_region].memory;

1622            fatal("mapping fb region\n");
1623        fb_mem = avivo_device->regions[fb_region].memory;
1624
1625        pci_iterator_destroy(iter);
(gdb)
