Subject: 2.6.20-rc3: bt878/bttv: Unknown symbols, despite being defined in
 module depended on

This seems a bit odd. As the bt878 module loads, I get the following
error messages, despite definitions in the bttv module that bt878
depends on:

# egrep '(bttv_read_gpio|bttv_write_gpio|bttv_gpio_enable)' /var/log/dmesg
bt878: Unknown symbol bttv_read_gpio
bt878: Unknown symbol bttv_write_gpio
bt878: Unknown symbol bttv_gpio_enable

SMP kernel, the cpu is an AMD Athlon(tm) 64 X2 Dual Core Processor 5200+.

Full dmesg output is at
http://bugzilla.kernel.org/attachment.cgi?id=9987&action=view (unrelated
bug, but same box).

Full config is at
http://bugzilla.kernel.org/attachment.cgi?id=9988&action=view (likewise).

Output of lspci -nn -vvx is at:
http://bugzilla.kernel.org/attachment.cgi?id=9989&action=view (likewise).
