Well, I don't think so. According to Documentation/x86_64/mm.txt:

"The paging design used on the x86-64 linux kernel [...] provides:

o per process virtual address space limit of 512 Gigabytes
o top of userspace stack located at address 0x0000007fffffffff
o PAGE_OFFSET = 0xffff800000000000
o start of the kernel = 0xffffffff800000000
o global RAM per system 2^64-PAGE_OFFSET-sizeof(kernel) = 128 Terabytes
- 2 Gigabytes
o no need of any common code change
o no need to use highmem to handle the 128 Terabytes of RAM"
^^^^^^^^^^^^^^
I have only 512 meg. ;-)

Sure. They are for 2.6.9-rc2-mm4, though:
