yes they can't work both equaly on the same pci ids.

so your bugreport needs to reach upstream,
so that your chipset regains support on the new stack.

this is kind of an expected fallout and no the old stack had
to many shortcomings that he won't be enabled.
the new stack is gaining enough momentum to have it's bug
shaken out for the next release of Lenny.
 
please file aboves report in bugzilla.kernel.org
and inform us of your bug nr.

thanks
