Thanks. For the record, I tested this both on 32-bit OVMF and on a
mixed mode tablet (with 32-bit AMI firmware) that I keep for testing
purposes. Notably, 32-bit OVMF boots with paging (and PAE) enabled
whereas the AMI firmware doesn't.

Not sure how many users of mixed mode remain and how invested they are
in upgrading to newer kernels, but decoupling it from the legacy
decompressor does help the cleanup work I am doing in that area.
