That was the kernel bug that bit me. It existed only
in a few rcX-bkY kernels, so I'm surprised you get this
with various kernel releases. 2.6.10-rc2 works fine.

That'll bite you in the ass sooner or later. Better find
out what causes this problem. The code which sets up
the hotplug environment is in linux/lib/kobject_uevent.c
(kobject.c in 2.6.9 or older kernels) and
drivers/base/firmware_class.c.
