Sorry, I've been busy the past few days (getting married and stuff), I
did look at the patch but didn't get around to send a reply.

I needed the following extra changes, after that it compiles and works
on my HP300:

Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
ttyS0 at MMIO 0x690011 (irq = 5) is a 16550A
ttyS1 at MMIO 0x41c040 (irq = 0) is a 16550
ttyS2 at MMIO 0x41c060 (irq = 0) is a 16550


Kind regards,

Kars.
