How to remove missing features and webparts?

I've moved and upgraded a 2007 teampoint site to my Enterprise SharePoint 2010 site. The site is up and running but I've got this nagging error about a missing webpart and a missing feature.

The features that were not compatable were not used so what SharePoint 2010 would allow me to remove has been removed. Now I have this error message that still needs to be dealt with.

[MissingFeature] Database [WSS_Content_2007] has reference(s) to a missing feature: Id = [75a0fea7-cd50-401e-af0e-782f3662a299]. The feature with Id 75a0fea7-cd50-401e-af0e-782f3662a299 is referenced in the database [WSS_Content_2007], but is not installed on the current farm. The missing feature may cause upgrade to fail. Please install any solution which contains the feature and restart upgrade if necessary.
[MissingWebPart] WebPart class [768ec641-8c6a-1cc6-6465-185094919a93] is referenced [1] times in the database [WSS_Content_2007], but is not installed on the current farm. Please install any feature/solution which contains this web part. One or more web parts are referenced in the database [WSS_Content_2007], but are not installed on the current farm. Please install any feature or solution which contains these web parts.

So, I'd like to remove the references from the database for the feature and webpart mentioned in the error. I can't seem to spot how to do that with stsadm, it reports that the feature is not installed which leads me to conclude that I just need to remove the reference from the db. Is there a SharePoint way to do this or am I destined to remove it manually from the db myself?
