So, is the USB not working after $n resumes on T4xx and T2xx (at least) 
now fixed in HEAD?  If so, it would be REALLY good to MFC whatever fixed 
it to 10 and hopefully to 9 before 9.3.

I need to do more tests on stable/9; it didn't work with the offered 
workarounds on 9.2-RELEASE (leaving VESA out of kernel leaves me with no 
screen on resume in console mode, setting sysctl dev.[ue]hci.*.wake=1 
fails to even start to resume) though if that works on 10 I'd give it a 
go, despite Darren Pilgrim's dvd1_to_memstick script failing to have pkg 
use any of the local DVD packages, which is why I went back to 9.2

I know you only like working on HEAD, but unless there's API/ABI reasons 
preventing MFC, it would be great to have 9.3 work in this respect .. my 
X200 is not useful for purpose if it won't suspend/resume 100% reliably, 
with USB, and I don't want to run 11 on it, it's needed for developing 
non-FreeBSD stuff (in freepascal, if that's not a dirty word here :) and 
for that it needs to be rock solid while travelling from place to place.

Indeed; last I heard was last July with unsolved USB issues on your 
T400, and the mysterious but related 'CPU0: local APIC error 0x40'

It's a bit disconcerting if fixes only ever make it into HEAD, for me.
