Section 18.1 of the FAQ says nothing about the size of the regs.  In
addition, issuing:

    info libc a int86

gives me this:

"Note: The `.x.' branch is a problem generator.  Most code expects the
`.x.' branch to have e.g. "`.x.ax'" members, and that they are 16-bit.
If you know you want 32-bit values, use the `.d.eax' members.  If you
know you want 16-bit values, use the `.w.ax' members.  The `.x.'
members behave according to `#defines', as follows:"

Sure looks to me like the regs are 16-bit, and would explain why the values
returned when you assumed 32-bit integers are garbage.

Later,
Matt.
