Comment # 5 on bug 66963 from Sergey

Tried to play with rv6xx_dpm_init(), but no luck at all.
Toggling init conditions leads to same system stuck.

Though if I put 'return -1' system seems to boot (screen is still off). And I
can connect via ssh, but dmesg shows NULL pointer dereference in
rv6xx_dpm_ebable(). Probably it is expected if init fails.
