The current SCx200 drivers use a fixed base address of 0x9000 for the
Configuration Block, but some systems (at least the Soekris net4801) uses a
base address of 0x6000.  This patch first tries the fixed address then - if
no configuration block could be found - tries the address written to the
Configuration Block Address Scratchpad register by the BIOS.
