[c-nsp] Mac Incompatibility with PPPoE?

Longshot here I know, but we're terminating SBC DSL on a 7204 VXR and using
PPPoE for IP assignment, etc. Clients using Windows-based PCs either
directly connected to the DSL CPE or behind a router have no trouble
whatsoever accessing the gateway and beyond. To be more specific, in the
case of either a 3rd-party router (pretty much any vendor) or Windows itself
doing the PPPoE negotiation, there is no trouble.
Clients using Macintosh OS X (many variants) can only ping to the gateway
(the 7204 VXR loopback interface) but not beyond.
* If I replace the Macintosh with a Windows-based PC on the _same DSL line_,
using the _same IP address_, I can traffic to the Internet without a
problem. It's not line-specific.
* I have manually set the MTU to 1492 using ifconfig in OS X.
Has anyone see similar behavior, or have any suggestions for troubleshooting
techniques? Some of the relevant config is below:
ip unnumbered Loopback5
ip route-cache policy
ip route-cache flow
no ip route-cache cef
peer default ip address pool sbc_bton_pool
ppp authentication pap
ppp chap refuse
ppp ipcp dns x.x.x.x x.x.x.x
