However I don't know really how to get information from kernel-code to solve this. thx in advance 14.05.2007 14:46 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (MingW32) - GPGrelay v0.959 iD8DBQFGSF2FAAomYJ1taN8RAnPfAKCdpnT+Uxa8a1Mc85TCyDzNwsvuQQCgzHIx f7V/XEWtWCa2IWtYjk7W7dg= =y/NM -----END PGP SIGNATURE----- --------------030404010708050502000302 Content-Type: text/x-vcard; charset=utf-8; name="lkwg82.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="lkwg82.vcf" begin:vcard fn:Lars K.W.
