Plain 1.3.68.

I've tested several scenarios:
Common to all is the patched (bzImage+initrd-1.3.66c) 1.3.68 kernel.
1.) With kerneld support enabled, kernel loaded high with ramdisk but boot-
device modules (scsi) loaded by hand (linuxrc was a link to /bin/bash).
=> error
2.) With kerneld support enabled, bootdevice compiled in, kernel loaded
low (zImage), ramdisk feature not used.
=> no error
3.) With kerneld support enabled, bootdevice compiled in, kernel loaded
high (bzImage), ramdisk feature not used.
=> error !!!
4.) Without kerneld support enabled, everything compiled in, kernel loaded
high (bzImage), ramdisk feature not used.
=> no error !!!
The last two seem most informative to me. It seems that kerneld and the
kernel loaded high don't like each other.
