I just tried 2.4.23-pre9 and the CD-ROM drive works again. Plug in the PCMCIA card, double beep, mount disk, read it, unmount, unplug card. A mysterious syslog message about a "bad special flag" that had always shown up has also disappeared. Seems like someone has worked on it :-) Anyways, thanks to all kernel developers, Thom P.S.: For those interested, the problem was about a PCMCIA CD-ROM on a Sony Vaio PCG-Z600NE that stopped working with 2.4.21/22.
