I was giving the remote buddy trial a spin on my iMac G5 with an eHome 2005 receiver connected and the driver does not appear to work.
Testrun has the following error: 
Set 1 .. 0

kextload: resolving dependencies for kernel extensions with validation and authentication failures 
kernel extension /private/var/folders/zz/zzzivhrRnAmviuee+++++++++++/TemporaryItems/RBIOKitHelper.kext has problems: 
Validation failures: 
{ 
"Executable file doesn't contain kernel extension code" = true 
} 
Warnings: 
{ 
"A personality matches on IOResources but IOMatchCategory is missing or not equal to its IOClass (driver may fail to win matching)" = true 
}
Installing the driver completely crashes my mac as soon as an ir command gets received.
Thanks in advance for any help!
