Just another data point. I've seen this issue also. It does not appear to be GRUB's fault. It 
appears the BIOS on the card does something funky as it also prevents syslinux/isolinux/pxelinux and 
its friends from properly detecting/reporting the machines memory. Machine has 16GB but a PXE boot 
believes it has 3GB.

I "worked around" the problem by swapping out the mainboard for a later model with a different BIOS 
and the problem went away. Not pretty, but it was the only way I could get the machine to boot with 
those cards in it. I have 4 IBM cards in 2 machines and they work fine here. I still have the dodgy 
mainboard and can set it up if you need help testing/reproducing the issue.

Regards,
Brad
