c0008010: __kernel_thread
c0004140: init
c01548b0: do_basic_setup
c015eb7c: device_setup
c015cc8c: net_dev_init
c015d480: ic_open_devs
c015dde0: ip_auto_config
c00762e0: dev_change_flags
c0075278: dev_open
c00d749c: de4x5_open
c00d7764: de4x5_init
c00d8de4: autoconf_media
c00df338: disable_ast
c000f104: del_timer

Appears to lose it in the kernel timer services.  I'll update my source
tree to the latest vger and give it another try.  My arch independent
stuff hasn't been updated since Nov 30.
