You can take a look at the KMS code and port the relevant changes to UMS. http://cgit.freedesktop.org/~airlied/linux/tree/drivers/gpu/drm/radeon?h=drm-fixes There isn't just a simple function to reset the chip, you need to reprogram the memory controller, the display hardware, etc. As your problem appears to be display related, I would take a look at the code in atombios_encoders.c and atombios_crtc.c in KMS and compare it to the code in atombios_output.c and atombios_crtc.c in the UMS tree. Your chip is in the PALM family and has a DCE4.1 based display block.
