I'm running the -rt kernel on F10 and it runs fine (both 32 and 64 bit
versions). That said, I expect any modern distro with an up-to-date
glibc will be perfectly fine for running an -rt Linux system.
I'd make my pick as to the arch based on how much memory you
anticipate stuffing into the system: more than 4GB, use 64-bit; less or
equal to 4GB, use what's native to the CPU. I generally use 64-bit
nowadays, but that's really just personal preference. Some folks still
claim that 32-bit is faster, but I haven't seen it.
