Can't set negative weight on a channel

Not sure if this is fixed in dev, but I noticed in the 6.x.2.1 (may have been reported, but I couldn't find it).

When you update/insert into ad_channel, if the weight is negative you get (from mysql):

Warning (Code 1264): Out of range value adjusted for column 'weight' at row 1

I think the data type needs to be changed, looks like it is a hodgepodge throughout drupal that people use to store weights, I have seen tinyint and int...hmm...
