What kernel is this exactly ? Those symbols seem to imply something is trying to do floating point in the kernel, which is totally forbidden. Most video cards need to be soft-booted (POSTed) some way before a kernel driver can use them. This require some firmware support, typically an x86 BIOS emulator, do you have that in dink32 ? Some fbdev's, afaik, can run a card booted from scratch (I think Matroxfb with earlier cards and some clgen but I don't know the details). Regarding __vmalloc, that should be defined (and exported) by the core kernel. Now, regarding he availability of the VGA space, that depends how your host bridge is configured, do you have a pass-through window to legacy VGA addresses on the PCI ?
