It's likely that uhci-hcd is just an innocent bystander here. The Ethernet
controller generates an interrupt request on IRQ 11 at a time when it should be
quiescent. Nothing happens until uhci-hcd loads and enables that IRQ line, at
which time the CPU receives the interrupt from the e100 device. Of course the
uhci-hcd interrupt routine doesn't handle it, and the e100 driver hasn't been
loaded yet. Thus you get the "Nobody cared!" message and the IRQ is disabled.
It's possible that under 2.4, the e100 driver loads before uhci-hcd. Obviously
that would prevent the problem from occurring. It's also possible that there's
something different about the way 2.4 and 2.6 initialize the e100 hardware, as
part of the PCI startup or even the ACPI startup.
