This change looks to be responsible for some confusing dmesg output. Here's some
diff between v2.6.35 and current Linus tree:


< Early serial console at I/O port 0x3f8 (options '115200')
---
> Early serial console at I/O port 0x1016 (options '115200')

Note that my serial port didn't move to a different address. Hex(3f8)
== Decimal(1016)

I think those two printk formats should be using 'x' format rather than 'u' :-)
