This is an inverted sentence, i.e. the subject is after the verb. Let me
rephrase it in the regular sentence order:

  Strange architecture ABIs seem to require more than 8 bits ...

The subject is 'ABIs' which is plural. Therefore it requires the plural
form of the verb 'seem', i.e. no 's' at the end. The inversion of the
sentence does not change that at all.

Think about this variant of the sentence:

      There are strange architecture ABIs ...

According to your logic this would be:

      There is strange architecture ABIs ...

which is obviously wrong, no?

I'm not a native speaker, but basic grammar rules are exactly the same
for native and non-native speakers as far as I know.

Thanks,
