Do normal region restrictions apply when playing PS1 games on PS3?

I got my PS1 while living in the US and I live in EU now. Will my US PS1 games work on a PAL PS3 or do normal region restrictions apply?

PS1 games are region locked, so you won't be able to play them on your PAL PS3.

Only the Classics downloads from the PSN are region-free, so if you create a USA account on your PAL PSN, the PS1/PS2 games from the USA PSN will work, same goes for Japanese games.
