My blocker is the lack of a working -append.  You have a git tree for a
collection of 5 patches, which then wants to invoke "quilt" to apply them. 
(Seems like overkill.)

At a guess, this seems like the patch that implements it is
staging/sh4-r2d-update-pci-usb-and-kernel-management.patch

No you don't, you just need a chainsaw and some duct tape...

I adjusted the above patch to apply to current qemu svn, and attached the 
result, but it didn't make -append work.  It's still using the hardwired one.

Any suggestions?  (Do I need to look at the other patches?  This one looked 
like it was _trying_ to fix the problem...)
