psb_intel_init_bios - initialize VBIOS settings & find VBT : DRM device

Loads the Video BIOS and checks that the VBT exists. Sets scratch registers to appropriate values.

VBT existence is a sanity check that is relied on by other i830_bios.c code. Note that it would be better to use a BIOS call to get the VBT, as BIOSes may feed an updated VBT back through that, compared to what we'll fetch using this method of groping around in the BIOS data.

Returns 0 on success, nonzero on failure.
