The 10.4u SDK version of IOPMAssertionCreate is not publicly supported.

Moreover, 10.4.x does not respond to the NoDisplaySleep and NoIdleSleep assertions that 10.5 does. So these invocations of IOPMAssertionCreate() are only valid in 10.5 and later.

Are you sure about that?
I just executed:
find /Developer/SDKs -name '*.h' -print0|xargs -0 grep IOPMAssertionCreate

and it only returned results in the 10.5 SDK [with no results for IOPMAssertionCreateWithName].
It's 10.5 only. You can read about it in the 10.5 IOKit release notes here:

I was looking in the linkages, not the headers:
nm -arch i386 /Developer/SDKs//MacOSX10.4u.sdk/System/Library/ Frameworks/IOKit.framework/Versions/A/IOKit | grep IOPMAssert 90c19ffc T _IOPMAssertionCreate 90c1a14e T _IOPMAssertionRelease

But I'm guessing that without a published prototype, Ethan is not going to want you linking aqainst it, as it might do something nasty...
