Ticket #1248 (closed defect: invalid)
CPUID doesn't expose "SYSENTER/SYSEXIT" in spite of supporting it

the CPUID-instruction passes through the cpu's name etc. but lacks the bit 11 (CPU_FEATURE_SEP) that indicates support for sysenter. I tried to alter a kernel that I have developed to skip the check for this particular bit and it worked. So there seems to be support for SYSENTER/SYSEXIT anyway.
