OK I have tested the sky2 driver in Breezy and have a mixed report.
Initially the network came up fine and dmesg showed:

[4294747.265000] sky2 eth0: enabling interface
[4294747.281000] NET: Registered protocol family 17
[4294749.226000] sky2 eth0: Link is up at 100 Mbps, full duplex, flowcontrol none
[4294752.177000] NET: Registered protocol family 10
[4294752.178000] Disabled Privacy Extensions on device c0337fa0(lo)
[4294752.178000] IPv6 over IPv4 tunneling driver

and ifconfig showed that dhcp had handed out a good address:

eth0      Link encap:Ethernet  HWaddr 00:11:11:40:FA:7D
          inet addr:192.168.0.100  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::211:11ff:fe40:fa7d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:105 errors:0 dropped:0 overruns:0 frame:0
          TX packets:72 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:34261 (33.4 KiB)  TX bytes:7582 (7.4 KiB)
          Interrupt:17

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:10443 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10443 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:968128 (945.4 KiB)  TX bytes:968128 (945.4 KiB)

I was able to ssh to remote sites and dns seemed to be working. In fact this bug
report is being done using the driver.
However I then launched firefox and when certain sites loaded (eg nytimes) no
pictures came up and the network froze.
At that point the router (192.168.0.1) was not pingable. I have seen a similar
problem a long time ago and it was then connected
with ipv6 problems. In dmesg the last line is

[4295331.141000] eth0: no IPv6 routers present
 
The above suggests that the driver works but still has bugs. If you want me to
run further tests let me know.
My networking skills are ok but definitely not advanced....
