[PD] no input from pwc via pdp_v4l

[metafor at gmx.net]

had to reinstall my laptop recently. unfortunately there were some
issues with the pwc driver since then. i followed the instructions
mentioned in pwcx-9.0/ patched the kernel (2.4.25) and made the modules. 
camstream ist working. but pdp pdp_v4l is complaining.
(tested with 0.12.4 & 0.13.0)

any ideas?
(i saw that olsen had the same problem half a year ago, but his thread 
died..)
