alc(4) link autoselect problem

Hi

On my recently acquired netbook (compaq mini-110), the ethernet
doesn't autoselect the link speed properly.  I think this is because
HP chose the cheapest ethernet controler and the cheapest PHY and
there's a speed missmatch (or the PHY isn't correctly detected):

alc0: <Atheros AR8132 PCIe Fast Ethernet> port 0xec80-0xecff mem 0xfebc0000-0xfebfffff irq 17 at device 0.0 on pci2
alc0: 15872 Tx FIFO, 15360 Rx FIFO
alc0: Using 1 MSI message(s).
miibus0: <MII bus> on alc0
atphy0: <Atheros F1 10/100/1000 PHY> PHY 0 on miibus0
atphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
alc0: Ethernet address: 00:25:b3:6f:ab:9a
alc0: [FILTER]

alc0_at_pci0:2:0:0:        class=0x020000 card=0x308f103c chip=0x10621969 rev=0xc0 hdr=0x00
    vendor     = 'Attansic (Now owned by Atheros)'
    class      = network
    subclass   = ethernet
    cap 01[40] = powerspec 3  supports D0 D3  current D0
    cap 05[48] = MSI supports 1 message, 64 bit enabled with 1 message
    cap 10[58] = PCI-Express 1 endpoint max data 128(4096) link x1(x1)
    cap 03[6c] = VPD

The AR8132 is Fast Ethernet, but the Atheros F1 is gigabit capable.
If I set the media to 100BaseTX full-duplex it works.
