Our previous release, 11.0, shipped with 2.4.something as the
stock kernel, but we did ship 2.6.18 as an optional kernel in
/testing.  That one is definitely too old, as it doesn't even
have SYSFS_DEPRECATED in the config:

  $ grep SYSFS config-generic-2.6.18=20
  CONFIG_VIDEO_PVRUSB2_SYSFS=3Dy
  CONFIG_RTC_INTF_SYSFS=3Dm
  CONFIG_SYSFS=3Dy

This should narrow down the search to 2.6.19 or 2.6.20 though.

For what it's worth, 12.0 was shipped on 20070630, and 11.0 went=20
out on 20061001.
