Can you create a switch to remove the "Other" option on contribution nodes?

Some clients have uses for the CRMAPI contribution form nodes that preclude the need for an "other" value (usually when there are a set of fixed values, say for an event, and no desire to have an open-ended field). Luckily the hooks on the other element are granular enough that I can hide it with CSS. But I'd really prefer to have a programmatic way to hide the div with the id of "edit-select-amount-other-wrapper" as well as the div with the class of "amount".
