Today I got HelenOS to run on beagleboard-xm qemu emulation to the
point some kernel tests pass (I have no idea whether the others just
take too long or hang).
The support is rather rudimentary:
serial port serves as kconsole input/output, there are no uspace
input/output drivers (I plan to get OHCI working)
I still have an issue with getting timer1 to work properly (switch to
32kHz clock source), too short timeouts cause hangs, as a workaround
you may apply this patch

the same bug is in creating identity mapping, I added comments in bbxm branch
j.v.
