Color me amused.  That was the original way to pass information
to hotplug agents ... back then (2.4.0.test10 or so), there was
usually no other way to export the relevant data.

I'd rather just guarantee that the sysfs device were fully
constructed (attributes and all) before the driver binding and
hotplug stages of enumeration started.  That's been a problem
all along, and that's what those recent changes were supposed
to be addressing.
