I get the "address .... already in use" message during plymouth splash:
[ 13.591205] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01
[ 13.591470] SP5100 TCO timer: mmio address 0xb8fe00 already in use
Running on an Acer Aspire One 522 (AO522) with 2.6.38-8-generic #42-Ubuntu.
Let me know if there's any more information I can provide or testing I can do. It's been a long while since I seriously used linux/unix though...
