I believe the current recommendation is to check for specific functionality rather than OS version for this kind of thing.
So, I you could check if multitasking is supported before registering for that notification.
(From the iPhoneAppProgrammingGuide:)
UIDevice* device = [UIDevice currentDevice];
BOOL backgroundSupported = NO;
if ([device respondsToSelector:@selector(isMultitaskingSupported)])
backgroundSupported = device.multitaskingSupported;
