The MIPS/Linux kernel today does not support the R10000 (there's a panic("CPU too expensive"); somewhere if the Processor ID for R10K is detected), but the CPU should not be at all difficult to support in the kernel - it was a design constraint of the R10K that it run the same Windows NT kernel as the R4400, so the CP0 is a pretty strict superset of the R4K. The hard part of an R10K/O2 port would be more in the drivers than in the CPU support. The O2 went for a high-bandwidth "unified memory architecture" design which has very little resemblence to any other Linux platform of which I am aware. I've seen references on this and other mailing lists to people working on getting Linux onto the O2. Hopefully, they will respond.
