My IOP331 arrived this week, courtesy of Intel, this will be used for working on OProfile PMU code initially, but perhaps some more 2.6 hacking later. I had a bit of a hard time getting it going initially but turns out my flash is bad, but switching to 16bit mode appears to make RedBoot happy to at least proceed to a prompt. That's good enough for me. Tonight i did the kernel changes for timer int based OProfile and got the PMU code to compile, tommorrow i'll wrap up OProfile userspace support and perhaps start on the PMU -> OProfile interface code. I just can't wait to start working on various PCI/PCI-X code/devices with this thing =)
