This may not help that much, but you should determine what
"-536870201" means. Here's what I did:
$ gdb
GNU gdb 6.3.50-20050815 (Apple version gdb-563) (Wed Jul 19 05:17:43 GMT 2006)

(gdb) p/x -536870201
$1 = 0xe00002c7
(gdb) q
Experience tells me that an error starting with 0xe000... is likely to
be found in IOKIt.
$ grep -riI 2c7
/Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/IOKit.framework/Versions/A/Headers
/Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/IOKit.framework/Versions/A/Headers/IOReturn.h:#define
kIOReturnUnsupported iokit_common_err(0x2c7) // unsupported
function
So IOCreatePlugInInterfaceForService returned "unsupported function"
I don't have more than that to offer. Good luck figuring out your problem.
