Ah, this was fixed another way in the upstream package, by using a 
different kernel interface (just a different sysfs file, really). That 
is the patch I then backported to the debian parted package. So there is 
no need to fix the kernel.

Note that I think it is useful to get this into the installer- it's a 
bugfix after all. However to be able to actually do something meaningful 
with it, we need an updated lvm2 package as well (working on that with 
upstream, I prefer to fix bugs in upstream packages first, then backport 
them), an updated mdadm package (only needs a few changes to the debian 
part, but the maintainers are mostly ignoring me), and ofcourse a few 
small(ish) changes to several installer packages. I haven't sent patches 
or filed bugs for the installer packages, trying to get lvm2 and mdadm 
fixed first.

Thanks

Mike.
