I saw some problems, but it may have been due to the KVM+PS2 dongle I was using on it.  There were reported problems with Windows+USB, so most likely this is a hardware issue.

Does SLES solve the USB port issues?

Using the kernel command line option 'acpi=noirq' works for installing FC/RHEL on the E521.  SLES10 appears to work properly out of the box.  I have not yet tested other releases on the E521.
