problem with yaboot/ybin on iBook

[Arrigo Benedetti <arrigo@vision.caltech.edu>]

I have two problems with  yaboot/ybin on an iBook where I installed Debian
2.2r3, Mac OS 9 and Mac OS X in separate disk partitions. I upgraded
to the latest ybin version.

1. After a reboot from Mac OS 9 I can't get into the open firmware menu
   pressing the 'option' key during boot. What I have to do is press the
   Command-Option-O-F combination, the 'boot hd:11,yaboot' from where I
   boot linux. In linux I run ybin which reloads yboot so at the next boot
   pressing the 'option' presents the three menu options.
   
2. At some point I had a graphical menu for the selection of the OS to boot,
   now the menu is text only. Why is that?

Thanks in advance,
