I *think* I have applied the patch correctly. Please find a copy of
"git show" in the build directory attached. This should be the right
thing, shouldn't it?

Maybe I forgot to speify a particular debug option / verbosity?

I've also confirmed that the "XXX ahci_set_ipm" is present in
libahci.ko. So either I've screwed up badly when compiling the initrd,
the code is not executed or the printout does not make it into any
logfile anymore.
