Yes and yes.

Basically, that vgainit.inc and this bit of code in northbridge_fixup()
was enough for running ADLO with binary VGA BIOS.
(also disable shadow ON/OFF code in loader.s)


                /* Turn on shadow DRAM at 0xC0000-0xFFFFF so we can write
                 * PIRQ table, VGA BIOS, Bochs BIOS, etc. */
                printk_debug("Enabling shadow DRAM at 0xC0000-0xFFFFF: ");
                pci_write_config_byte(pcidev, 0x61, 0xff);
                pci_write_config_byte(pcidev, 0x62, 0xff);
                pci_write_config_byte(pcidev, 0x63, 0xf0);
                printk_debug("done\n");


I also changed raminit.inc to work with my 256MB PC133 DIMM,
and now improving it to detect memory (size and MA type) automatically.
