You could leave xc_hvm_build_target_mem as it is and implement
something similar to:
+ if ( gfx_passthru )
+ sts |= setup_vga_pt(xc_handle, domid);
+ else
+ sts |= init_vgabios(xc_handle, domid, NULL, 0x800);
in pyxc_hvm_build instead so that there is no need for API changes and
the vga bios would still be read from a process in dom0 (xend in this
case).
