-r6 puts our pm-utils package to same level (and above) with Debian's pm-utils package no regressions were (except for bug 514480 which turned to be bogus) reported, so, please test and stabilize: =sys-power/pm-utils-1.4.1-r6
arm stable
amd64/x86 stable
ppc/ppc64 stable (admitting I've only tested 64UL), sparc stable (experimenting with v8)
Stable on alpha.
ia64 stable (no arch specific changes from -r2, should be, and is, safe)
