No no no! “Awoken” is correct, and sounds just fine to me. You wouldn’t say “I would like to be award the Victoria Cross,” would you? “Awaken” is the infinitive; you should use the past participle “awoken”, or “awakened” if you prefer.
My dictionary actually prefers “awake” as the verb to “awaken”, with the past participles “awoke” or “awaked”. These sound more horrible to me.
Another nitpick - it should strictly be “I should like to be awoken at 8am,” but this does sound rather starchy these days.
Just rereading your last entry - you are changing the meaning of the sentence.
“I would like to be awoken at 8am” means “I would like someone to come and wake me up at 8am”.
If you change it to “I would like to awaken at 8am” (which is still grammatically correct) it means "I would like to wake up at 8am, but I’m not actually asking anyone to do anything about it)…
We subeditors live for pedantry. (And I’ll bet I’ve made plenty of typos in this post )
