just to be clear, the only insn you need is:

the kernel docs say sr2 holds the kernel gateway page (so i guess
0x100 is a
known offset into that). the docs don't mention r0 that i can see,
so i'm
guessing it's one of those "always 0" registers ?
Yes. There is also an entry at offset 0xb0 for light-weight-
syscalls. Currently,
this implements an atomic CAS operation used for pthread support.
