Andrew Vasquez <andrew.vasquez@qlogic.com> found the problem. The 2.4
driver was forcing the data rate to auto negotiate, while the 2.6 (or
8.x series) driver was honouring the NVRAM setting which was at the
default 1 Gbps. Changing to auto negotiate in the qlogic BIOS fixed the
problem.

It's a 64 bit slot..
