It is in fact identical. Disassembly with the tools found on sourceforge
was fun, since they have endianness bugs, don't recognise the 'JMP'
which was the first instruction, and need each 3-byte instruction in the
binary to be prefixed with a zero byte to make it 4 bytes. But after
sorting that out and going through it instruction by instruction, it
really does seem to match. Thanks very much for digging it out.

When you say 'GPL like the driver it came from', actually the driver
doesn't specify any version of the GPL but does refer to the top-level
COPYING file. So we'll take that to mean 'GPLv2 and not later', like the
majority of the kernel. OK?
