The patch is missing the original Signed-off-by from Marc, and your
Signed-off-by.

This part breaks the majority of all boards in v2 (checked with abuild).

E.g. on asus/p2b:

./buildrom linuxbios.strip linuxbios.rom payload 0x10000 0x20000
linuxbios image is 192277 bytes; only 65536 allowed
Linuxbios input file larger than allowed size!
: Success
make[1]: *** [linuxbios.rom] Error 2
make[1]: Leaving directory `/tmp/v2/targets/asus/p2b/p2b/normal'
make: *** [normal/linuxbios.rom] Error 1

There must be some other way to fix this.
