Nope, 1000Base-T (no X) is speced for Cat5 cabling..  As per the 802.3
spec 40.1:
1000BASE-T signaling requires four pairs of Category 5 balanced cabling,
as specified in ISO/IEC 11801:1995 and ANSI/EIA/TIA-568-A (1995) and
tested for the additional performance parameters specified in 40.7 using
testing procedures defined in proposed ANSI/TIA/EIA TSB95.

It's wierd that it works at 100Base-TX w/ Cat5, but not w/ Cat5e...
Is there differences in the cable length or something?  Have you tried
w/ just normal Cat5?
