I believe all added variables between the last version of the boot

how likely changes in arch/x86/boot/ have been regressions in the 32bit
entry point support.
As for solving this there is a simple solution. Add a second jump
right after the first jump. The variables after the second jump can
all be zero initialized.
could use .org to force start_of_setup start from 0x1000
but how about area before setup_header ? how it is full of EFI_STUB suff there.
Yes, it doesn't really solve the problem I fear.
