has anyone been able to use AutoYast with PXE boot on a tg3 based machine?

Hi folks: Not directly autoyast, but one of the supporting utils ... My machines have Broadcom chips that map into the tg3 driver. I set up autoyast as per the howto posted here recently (thanks!), and tried the boot. It probes for an RTL8139 and hangs. They units are Tyan S2882 based, and work fine when booting by DVD. From what I read, the issue are the drivers compiled into grub (pxegrub to be precise). Has anyone a working rpm or build of grub with the relevant patches, or a pointer to them? This is on a SuSE 9.2 AMD64 unit. Thanks! Joe
