What you describe is definately not a Remote Buddy problem:
1) Remote Buddy only attaches to one device - being your Keyspan IR
Receiver. The hub, to which all other devices are connected, is up two
to three levels in the driver tree, including a kernel/userspace
barrier that Remote Buddy can't cross (no userspace clients are
available for IOUSBHub objects AFAIK - and even if they were, Remote
Buddy does not look for or use them).
2) Remote Buddy generally has no interest in hubs and leaves them
completely alone.
3) Built-in trackpad and keyboard are internally connected through
USB, but usually they're connected via a different, internal port / hub.
4) On a PowerMac with Keyspan IR receiver (as in your case), Remote
Buddy's kernel extension does nothing USB related at all. As of now,
the kernel extension only contains code relating to built-in IR
receivers and Keyspan *RF* Remote for Front Row.
There's been a lot of coverage on a bug of the (re)new(ed) USB stack
in Leopard that causes the exact problem you describe. Here's a
randomly selected article:

You may want to file a bug with Apple at
http://bugreporter.apple.com/
to inform them about the problem.
That said, here's a short update:
The (different) problem that built-in IR receivers are sometimes not
found after a wake on Leopard is also related to changes in Leopard's
USB stack and requires a somewhat more complex, pretty code-intensive
workaround and a completely new design approach, which I've almost
finished.

Oops... I found why RB wont work on my PM G4, when i have my Keyspan
IR remote conncted to my mac with RB running and put it to sleep the
USB port stops working, nothing will work on it. Mice, keyboard and
USB-flash memory, i will test it on my other USB-port today.
