IA64 inherits this part of the architecture from x86, so no magic fix. This is a fundamentally a chipset limitation, not an architectural bug.
rev-E amd64 cpus from AMD all have memory hoisting support, as do all server chipsets from Intel for the last several years.
To avoid this you just need a good chipset and a good BIOS implementation. Any recent server board should be fine. Hopefully the desktop boards will catch up soon.
