Dear Gerd,

Small nit for the commit message summary: Increa*s*e.
BUILD_MIN_BIOSTABLE reserves space in the f-segment. Some data structures -- for example disk drives known to seabios -- must be stored there, so the space available here limits the number of devices seabios is able to manage.
Do you have an example command how to reproduce this with QEMU?
This patch sets BUILD_MIN_BIOSTABLE to 8k for bios images being 256k or larger in size. 32bit code is moved off in that case, so we have more room in the f-segment then.

Rest looks good.
Kind regards,
