The non-1GB-aligned ones need to be disbarred when PAE is on, I think.
Well, right now _all_ the non-3:1 cases need to be disbarred. I think
we depend on the kernel mapping only ever being the _one_ last entry
in the top-level page table, which is only true with the 3:1 mapping.
But I didn't check.

No. It works fine (or seems to) with 2:2 mapping. I've tested with these
extensively

The boundary for 2:2 with the current patch is 0x78000000, not 0x80000000.
It may still work, but nobody's checked yet.
cheers
