I wish this were always true. I tried to get rid of the memory hole, but
then my nice 64 bit Linux kernel would crash (or better get in an infinite
loop) upon initialising the Yukon Gigabit Ethernet NIC (i.e. immediately
after loading the sk98lin module). Actually, to be more specific, it locks
up not when loading the driver, but the first time anything attempts to use
the NIC, sending any traffic through it.
The same kernel boots and works ok with the memory hole, therefore I decided
I preferred to have a working computer with ~300Mb less than a locked up
computer with 4Gb...
