looking for a usb kvm switch box with audio

[skanky]

with my old t42, i had to get a belkin usb KVM switch box (intergrated cables) as it didnt get past the ibm splash screen with a ps2 switch box.

that has served me well but now i'm after one for my t60 that has an audio output to switch sound devices, does the t60 suffer from the same boot problem with switch boxes as described above?

edit: i think this http://www.trustedreviews.com/periphera ... Support/p1 is the version of the kvm i have, but with audio. any good for thinkpads?

or are IOGear kvm's any good? http://www.iogear.com/main.php?loc=prod ... M%20Switch
