See PR 23481 for some related context.  I had that same problem (bad MAC address detection and no PHY detection) with 1.6.2-RC4.  In current (if_sip.c rev 1.86), the address and media detection/autonegation work fine.  However, I can't actually get packets out (or maybe in too).
After failing to send packets, it reports "sip0: device timeout".

The probe messages are thus:

sip0 at pci0 dev 4 function 0: SiS 900 10/100 Ethernet, rev 0x91
sip0: interrupting at irq 5
sip0: Ethernet address 00:10:dc:98:ed:b7
ukphy0 at sip0 phy 1: Generic IEEE 802.3u media interface
ukphy0: OUI 0x000004, model 0x0020, rev. 1
ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

FWIW, the specs for my motherboard (MSI 651M Combo-L) say what it has is
"SiS 962L integrated MAC + RealTek RTL8201BL PHY".  This hardware works fine under Linux 2.4.22.

Bring up sip0.  Try to use it (e.g. dhclient).  No packets seen on the wire.  After a few seconds trying to send packets, "sip0: device timeout" seen.

I would be happy to do anything I can to help debug the problem,
but I don't really know where to start.  BTW, I really want to be running the stable branch.  I backported the if_sip.c changes from -current to 1.6.2-RC4 and that solved the problem of not detecting the PHY/media/address, but behaves in the same losing way for actual packets.
This report is for the -current kernel, though I hope to backport the fix to 1.6.2 after it's resolved in -current.
