I've got a Thinkpad Z61t, which is somewhat similar to yours (although I 
do have the Intel wireless).  To be honest, I didn't even try CentOS on 
it, figuring the hardware was too new.  I initially installed FC5, which 
mostly worked, except for standby mode (it'd go to sleep, but not wake up) 
and some video issues (vesa worked, i810 required an out-of-band upgrade 
but even then GL still crashed).  Over the weekend I upgraded to FC6, 
which is actually quite nice.  The video works very well now, and standby 
and resume works (except that I can't quite get wireless working after a 
resume, but I'm not sure if that's due to lack of trying and/or the 
complication that I'm also using WPA2).

I'm fairly certain that you'll need xorg-7.1 to get video working natively 
(rather than via vesa), which means FC6 or wait for CentOS5.  And to have 
a hope of standby working I'm pretty sure (bot not positive -- did the 
AHCI suspend patches go into 2.6.18?) you need the hard drive in 
"compatibility" mode rather than AHCI.

As for your wireless, a little bit of googling seems to indicate that 
bcm43xx has issues with it, and ndiswrapper is the way to go.

Good luck.
