The garbage is probably because the oscillator frequency is wrong.
The driver tries to use 25Mhz, but I bet the prom 'clock' property
is set to a non 25 value.  I just made a change to OpenBSD's magma
driver that allows us to properly decode the prom 'clock' node and
do the right thing (der Mouse, you'll run into this too when trying
to support your board).
