since this patch SeaBIOS no longer detects the PS/2 keyboard. This means
there's no keyboard in SeaBIOS, GRUB or FreeDOS. OVMF and Linux detect
the PS/2 keyboard without issues.
Here are a few lines from the SeaBIOS debug log.
table(50434146)=0x007e1971 (via rsdt)
ACPI: parse DSDT at 0x007e0040 (len 6449)
parse_termlist: parse error, skip from 92/465
Scan for VGA option rom
Running option rom at c000:0003
Start SeaVGABIOS (version rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org)
and later
SeaBIOS (version rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org)
ACPI: no PS/2 keyboard present
it was a bug on SeaBIOS side, we need it to parse Alias term in AML
instead of choking on it

PS:
it's probably too late for it to make into 7.2
The proposed patch works.
It may still be an option to revert the commit 47a373faa6 (acpi: pc/q35:
drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration
generate AML). If an older QEMU version is migrated to QEMU 7.2.0 and
later and the guest reboots afterwards, it may end up without a working
keyboard because the migrated SeaBIOS is an older version.
With best regards,
