I'll have to do a bit more debugging here then. It seems that my driver did not fill the line_length member of fb_fix_screeninfo, and no gets was copied by fbcon when this is missing. I filled in this field, but now BUG: unable to handle kernel paging request at virtual address c882a800 [] mbarcfb_imageblit+0xc/0x20 [mbarcfb] [] soft_cursor+0x15d/0x1bc [softcursor] [] bit_cursor+0x338/0x5a8 [bitblit] [] vsnprintf+0x303/0x690 happens. Back to do some more debugging.
