After a bit more investigation, yes, it is kassert (kernel diagnostic assertion "viadrm_pci_ids[i].subvendor == PCI_ANY_ID" ), doesn't matter amd64/i386. The cause seems pretty obvious: viadrv_PCI_IDS doesn't include some chrome graphics like 0x7122 from VX900 or 0x122 from VX800, thus subvendor value is 0 by default, PCI_ANY_ID is 1 on the other hand, if I am not mistaken. Adding 0x7122 to the list allows viadrmums to attach and boot, but with some errors in the logs.
