After looking more into this problem, 0xC00000 is probably OK (don't know
details about POSTing non-primary VGA cards but looks like VGA is enabled so
this can work).

The problem is that after POSTing, the ATOM signature disappears from the BIOS!
I've dumper the BIOS from the rhdAtomGetDataTable() function using this code:

    if (atom_romhdr_off + sizeof(ATOM_ROM_HEADER) > BIOSImageSize) {
        xf86DrvMsg(scrnIndex,X_ERROR,
                   "%s: AtomROM header extends beyond BIOS image\n",__func__);
        return FALSE;
    }

+    FILE *f = fopen("/opt/rom.bin","w");
+    fwrite(base, 1, BIOSImageSize,f);
+    fclose(f);

    if (memcmp("ATOM",&atom_rom_hdr->uaFirmWareSignature,4)) {

When the card is primary, the file is 64512 bytes, contains ATOM signature and
works. When the card is secondary, the file is only 49152 bytes and the ATOM
signature is missing (see attachment).
