i don't know why "Learning GNU Emacs" says that...

the regexps in auto-mode-alist are matched against the _complete_
filename, hence we have to consider the directory in which the file
lies. to the best of my knowledge no filesystem on which emacs runs is
completly flat (no directories) so "^mymakefile$" will never match
anything. i believe "/mymakefile$" is what you are looking for. 

when i open ~/.bash_profile emacs correctly loads sh-mode, here's the
relevant part of auto-mode-alist:

 ("\\(/\\|\\`\\)\\.\\(bash_profile\\|z?login\\|bash_login\\|z?logout\\)\\'" . 

notice that there's no initial "^" in the regexp. (i don't know what
the "`" char at the start of the regexp is for.)

Ring the bells that still can ring.
Forget the perfect offering.
There's a crack in everything.
It's how the light gets in.
