I've run 2900xl's connected to each other though 2 ports each configured with: port group 1 distribution destination but never tried it with anything non-cisco.
This should give you what you need when doing 802.3ad LAGs:
interface FastEthernet0/21 port group 1 spanning-tree portfast ! interface FastEthernet0/22 port group 1 spanning-tree portfast !
It might have been the lack of STP portfasting that gave you trouble initially as the Linux LACP might have timed out waiting for STP discovery to finish.
Here is a good wiki article on link aggregation: http://en.wikipedia.org/wiki/Link_aggregation
I did not know linux used a higher part of the networking stack to negotiate protocols. That's interesting.
And here is a good site on Linux bonding interface: http://www.linux-foundation.org/en/Net:Bonding
You only need to setup port groups when doing 802.3ad, if you use the other methods you may need to tune out the 2900XL for the constantly shifting MAC addresses.
