You should probably read up on GNU assembler first; Google should find
plenty of hits. Some good ones:
- http://www.delorie.com/djgpp/v2faq/faq17_1.html
- http://www.ibm.com/developerworks/library/l-ia.html

For example, 'movw $_raw_scan_code, %ax' is presumably meant to move
the value of ax into a 'raw_scan_code' variable, but remember that
AT&T syntax is generally 'source, destination', and the $ is not
needed here (you are getting the address of the variable there, then
trying to move it into a 16-bit register, which is the cause of the
error message), and you need to double the % signs when writing actual
register names in inline assembly, so it should presumably be more
like 'movw %%ax, _raw_scan_code'.  You could also use the input list
to avoid needing to mangle the name by hand.
