Upgrading 4.0 to 5.1?

I'm currently using a 4.0.27 installation I inherited from someone else.
I'd like to upgrade to 5.1(.15) - bells, whistles, bugfixes, security
- yay.
1) The docs at "http://dev.mysql.com/doc/refman/4.1/en/upgrade.html"
appear to suggest moving to 4.1, then to 5.0, and then to 5.1. (With a
dump and restore for each move.)
2) However, my usage is light: a handful of tables, no more than 300
rows, no messing with character sets, nothing strange or complicated.
Is making the jump directly to 5.1 that risky?
