suspend for raid devices?

["Malcolm Herbert" <mjch%mjch.net@localhost>]

For portability and DR reasons I have set up my laptops so that the
internal disk is under RAIDFrame management as one half of a broken
mirror - this also allows me to boot my wife's laptop with the
still-beating HDD from mine in a USB caddy with no ill-effects if I have
to ... 

This works very well in most situations[1], however the version of
-current I had at the time (5.99.15 from mid-July) did not allow me to
suspend the laptop as the raid device lacked power management.  dmesg
has this to say:

|# zzz
|Suspending system...
|# dmesg | tail
:
:
|acpi0: entering state 3
|Devices without power management support: raid0
|acpi0: aborting suspend

I'm not sure what support is needed, however I was wondering whether it
was available now in a current kernel, or if not, how likely would it be
to be implemented?

Regards,
Malcolm

[1] except that this version of the kernel panics whenever the mirror is
detached ... :/
