Looks like you ordered wrong HP 128MB simms. The correct type to look for is "D4893A". If you noticed smell and smoke, take a look at the simm socket itself and see if there's any burned plastic that may have leaked over a pin, which may potentially disable a good contact with it and the memory module.
In any case, those HP modules may be of wrong voltage. I would not use them again unless you are absolutely sure that they are "D4893A" type, which have been confirmed to work with Blizzard accelerators.
