I have not worked with X86_64 kernels, so this is a shot in the dark, but could there be a compile time option for the amount of memory it supports like there is for the i386 kernels? I would not expect a problem at the 2G boundary with a 64bit processor. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
