If you are running Xcode 4.1's gdb on your debugger machine, you don't need to generate a .sym file with kextload -s. Instead you can target remote-kdp in gdb (on your "remote computer") and do

(gdb) add-kext ~/XXXX.kext

and gdb will get the addresses of where your kext was loaded directly from the kernel of the Lion system that's in kdp mode. (the kextload -s command that was used previously was the old way of telling gdb where everything got loaded)

Is that Lion only? Because, hot damn, that is cool!

Yeah, it requires the Xcode 4.1 gdb on the debugger-system and it requires a Lion kernel on the debuggee-system - there is a new structure added to the kernel in Lion which gdb reads to get the kext list. Earlier versions of the kernel didn't have that structure so we have to use the old method with the .sym files.
