tg3 driver - trying to get the old v0.99 driver woking on RedHat 2.4.18-10

I'm curently locked in to using this old RedHat 7.3 with the old 2.4.18 kernel. I need the see what's going on with skbuffs in the ethernet driver, in this case the broadcom bcm5700. When running 2.6 I use the tg3 driver and it's wonderfull. Getting the Broadcom driver to like without being a module looked more difficult that just using an older version of the tg3.c driver. I updated the old 0.99 version (Jun 11, 2002) to know about the Serverworks Card:

	{ PCI_VENDOR_ID_ALTIMA, PCI_DEVICE_ID_ALTIMA_AC1001,
          PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0UL },
        { PCI_VENDOR_ID_ALTIMA, PCI_DEVICE_ID_ALTIMA_AC1003,
          PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0UL },
        { PCI_VENDOR_ID_ALTIMA, PCI_DEVICE_ID_ALTIMA_AC9100,
          PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0UL },

        { PCI_VENDOR_ID_SERVERWORKS, PCI_DEVICE_ID_SERVERWORKS_0X14,
							/* Piet */
          PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0UL },
        { 0, }

and the device is matched ok now. Unfortunately when it does the probe it fails:

What does "fetching invariants of chip" mean?

I thought one of you guys might have a suggestion.

The tg3 driver looks cleaner than the Brodcom addon. I could also modify the driver so it doesn't have to be built as a module.
