MVME5500 1 Gbit Ethernet no longer works

I recently bought 2 new MVME5500 boards from Emerson. They have changed
the chip that supports the 1 Gbit ethernet interface from an Intel
82544EI to an Intel 82545GM. As a consequence, the 1 Gbit interface no
longer works, and the BSP issues the message:
"i82544EI device ID not found"
Has anyone seen and fixed this? Might it be as simple as accepting the
PCI Device ID of the new chip? I'm using RTEMS 4.10.2. I looked at the
newest version and it seems to be the same code. I have not yet probed
into the hardware to see what ID value is being returned.
The ID of the older 82544EI is 0x1008 (from
"cpukit/include/rtems/pci.h), which according to the 410 page Software
Developer's Manual is the default value if the EEPROM is not programmed.
