John, MSI capabilities registers are present on virtually all "bge" controllers but many of the "older" controllers don't correctly support MSI due to a chip errata that prevents MSI interrupts from actually being disabled during an ISR. Check the Linux code for the test used in tg3_open() which determines which controllers can actually use MSI correctly.
Even with the bug the older controllers will appear to work correctly on a heavily loaded system for short periods of time (sometimes even days) but they will eventually fail.
