Sound, ethernet, modemsndconfig identified the ESS Maestro 3i card and sound works fine. I also had no problems with the ethernet card. The modem is a WinModem for which there is no Linux driver (according to Rob Clark's site).
CD WriterThe CD writer replaces the floppy drive. You must reboot after switching between them. You can read from the CD writer by mounting /mnt/cdrom1. To be able to record with the CD, add this line to the linux boot entry in /etc/lilo.conf: append="hdc=ide-scsi"
Now reboot (the ide-scsi module is automatically loaded by /etc/rc.d/rc.sysinit). I've been using xcdroast (as root, I had problems making it user-runnable), and it works great.
Toshiba PDR-M5 digital cameraTo use the usb connection with this camera, use the usb-storage driver (run insmod usb-storage). Now create an entry in /etc/fstab so you can mount the device: /dev/sda1 /mnt/usbcam vfat users,noauto,ro 0 0
Now you can simply mount and umount it (of course you have to create the /mnt/usbcam directory first). It is read-only, so you can't delete images from linux (the camera manual recommends only deleting with the camera anyway).
