Attached you'll find a patch for the Philips Webcam Driver version 8.7.
This is a jump from 8.5, since 8.6 never officially made it into the 2.5
series due to rapid changes and incompatabilities.

The biggest changes include (from the Changelog)

8.7

* Incorporating changes in ioctl() parameter passing
* Also changes to URB mechanism
* Updating copyright information

8.6

* Added ID's for Visionite VCS UM100 and UC300
* Removed YUV420-interlaced palette altogether (was confusing)
* Removed MIRROR stuff as it didn't work anyway
* Fixed a problem with the 'leds' parameter (wouldn't blink)
* Added ioctl()s for advanced features: 'extended' whitebalance ioctl()s,
  CONTOUR, BACKLIGHT, FLICKER, DYNNOISE.
* VIDIOCGCAP.name now contains real camera model name instead of
  'Philips xxx webcam'
* Added PROBE ioctl (see previous point & API doc)
