Could you clarify which combinations did/do work
If I understood you correctly, it is something

2.6.26 + 0.7.0.99 = no kernel crash, successful umts connection
2.6.29 + 0.7.0.99 = no kernel crash, no successful umts connection

2.6.26 + 0.7.1 = kernel crash, no successful umts connection
2.6.29 + 0.7.1 = kernel crash, no successful umts connection

Is that correct? What udev version do you use?
FWIW, the kernel crash is most likely a bug in the kernel driver.

Could you also send me the output of
NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon
after stopping NetworkManager (/etc/init.d/network-manager stop)
