Just a couple high-level comments:
Is this code entirely written by you?
If the code is i386-specific, I'd like to see it put into i386 namespace.
The use of bitfields worries me, especially if the code might be
ported to other architectures. I can see now why you put __packed__ on
all your structs, as it is necessary to get anywhere close to the
right behavior from the compiler when using bit fields.
