Bootdisk and Crystal build based on SVN rev. 7067

Hi all!

I've built a default bootdisk and crystal target based on latest SVN rev. 
7067, with some patches from Submaster: 2006020522113805544 
2006020522115605589 2006020522122705693 2006020522124205748 
2006020522125305803 2006020522253706229. Note that none of these patches is 
strictly required for this type of build.

The resulting bootable ISO installs fine on the PC emulated by qemu 0.8. I 
didn't test the X server or KDE so far.

I noticed one udev related problem: when booting, /dev is mounted and 
udevstart is run early from /etc/initscript. Then other init scripts are run, 
e.g. /etc/rc.d/init.d/hotplug   and /etc/rc.d/init.d/udevd. 
Because only udevd is run from /etc/rc.d/init.d/udevd, not udevstart, device 
files for devices detected by the hotplug init script won't be created until 
udevstart is started manually.

I've fixed this by adding a line running udevstart to /etc/rc.d/init.d/udevd, 
see https://www.rocklinux.net/submaster/smadm.cgi?i=2006020819482101578 .

With best regards,
