The T23 doesn't have / do USB 2.0

No it's not, but I don't know what it is either; mine has that in dmesg
also, and my dmesg for uhci / usb ports 0-2 appears identical to yours.

 > i have compiled ehci in kernel

It's in GENERIC anyway.  If the T23 had USB2 ports, ehci would use 'em.

You can use a USB2 pccard if you need to, check the compatibility list.

Re your prior ACPI message: make sure you've applied the latest BIOS and
EC updates for the T23 model you have first; if you're still seeing ACPI
errors/warnings after that, maybe post them to the mobile or acpi list.
Searching the archives of either list for T23 should provide some clues.

My T23's BIOS and EC aren't up to date, I get a subset of your list of
ACPI messages (apparently harmlessly) but nothing like as many as you.

Adding acpi_ibm_load="YES" to /boot/loader.conf is a good start.
