although bulk downloading the data from the HapMap ftp site and process it yourself as Pierre suggests would be the most appropriate thing to do (I suggest you too to go to the latest ftp relase folder currently 2010-08_phaseII+III, download all the chromosomes data, and parse all that files looking for the SNPs of your interest), I understand that you may think "why should I deal with all that bunch of files if they have already done so?". if that is the case and you want to use the BioMart retrieval tool on top of HapMap you can also obtain the data you are interested in from there.
I have tried in the past the capabilities of such retrieval tool, and I didn't find any limitations in terms of query size. I'm sure it should be capable of letting you download all the data you are interested in by uploading a bunch of rs numbers on a single file as the only filter, and selecting the attributes you need (frequency, MAF, strand, ...). note that the HapMap version this tool handles is the #27 release, and not the current #28 release, so go ahead if you can live with that. if not, you will need to consider the original bulk parsing suggestion.
