If I remember correctly, the sysenter instruction is not present on AMD
processors. But it really doesn't matter as the normal int $0x80 approach
on an AMD is faster than sysenter on a P4...

Does anyone know...

According to AMD Processor Recognition Application Note, the SYSENTER and SYSEXIT instructions are supported on AMD Athlon and Duron, but not on K6 (see tables at the end).
