The controller reported is not consistent, it is labeled as both a
5702 and 5703 controller in the messages above.  It looks like there
is an invalid assumption in the routine bge_lookup_rev().  This 
routine assumes that each chip version will have a unique ASIC ID
which is incorrect.  Sadly, the 5702 and 5703 share the same ASIC IDs
so an additional test for the PCI device ID needs to be added to
discriminate between the two.  The ASIC IDs for the 5702 are as
follows:

#define BGE_CHIPID_BCM5702_A0		0x10000000
#define BGE_CHIPID_BCM5702_A1		0x10010000
#define BGE_CHIPID_BCM5702_A2		0x10020000

	{ BGE_CHIPID_BCM5702_A0,	"BCM5702 A0" },
	{ BGE_CHIPID_BCM5702_A1,	"BCM5702 A1" },
	{ BGE_CHIPID_BCM5702_A2,	"BCM5702 A2" }

Your controller is actually a BCM5702 based on the PCI device ID.

I tested with a 5702 A1 card and the v1.141 version still worked for
me.  Are you using a NIC card or is this a LOM?  If the latter, what
system is the LOM built into?  This error message indicates that the
controller was unable to read and load firmware from the NVRAM which
is usually a real error (unless the system was designed to operate 
without NVRAM which is generally only a few Sun systems).
