Can we build an SSDT that includes the contents of fw_cfg (e.g.
FW_CFG_SIGNATURE at offset 0, FW_CFG_UUID at offset 4, FW_CFG_NOGRAPHIC
at offset 16... the entry <-> offset mapping and the defaults would be
part of SeaBIOS), and then read that data from normal DSDT methods?
That would be similar to Gerd's patch, but without letting the OSPM use
the real fw_cfg device.
