Well, patching genkernel worked so its still broken as regards
suspend/resume - so I can now suspend/resume still with some errors.

Next problem is that there are error messages implying /usr might not be
mounted by the initramfs (some /usr files not found) ... is there
anything else that needs doing?  Once the system is up /usr and all
other directories are correctly mounted (most are on LVM).

Is there a way to get a detailed log of what the initrd is doing/has
done?
