Please post your lspci -vv results.
PCI-X has two speeds IIRC: 100MHz and 133MHz.  By definition it sets
the bit that older PCI versions used as 33/66MHz, so lspci will say
66MHz always for PCI-X, that's expected.  There's another bit of info
though, that's like:  +/-133MHz

where -133MHz  indicates it's running at 100MHz
and +133Mhz indicates it's running at 133MHz.

So look closely...
