Ahem... I forgot that you need a recompiled kernel for it to work.
Or at least arcane and forgotten commands like partx. Personally, I
like the partx way better. With the attached patch to util-linux
you can use partx.
Make sure no partition on sda is in use (swap/suspend/mounted), then
# partx -d /dev/sda
# kpartx -a /dev/sda
Now /dev/sda[1-15] have vanished and /dev/disk/by-name/sda[1-255]
appear instead. Mounting these devices works normally.
I also added this to
https://bugzilla.novell.com/show_bug.cgi?id=214992#c12
