my mobo manual says

2 184-pin DDR sockets
supports DDR266/DDR200
supports up to 2 un-buffer double sided DIMM DDR266/DDR200
supports up to 2GB max
supports only 2.5V DDR DIMM

so can I stick 2 of these ram sticks in there? or am i wrong?

Yes, You can use 2 sticks...but would advise to get a matched pair, both from same source, same brand etc.

I say you can, because you mention 2 slots at 2 gig max, meaning each slot can take a gig. On some boards each slot has a max it can handle. Also get it from zipzoomfly, excellent service compared to most other places and gets it to you fast.

The link to zipzoomfly had ECC Registered RAM...

Good catch copy, I wasnt looking that deep, but they do sell non-ecc.

MadDash24_7, 1 GB non-ecc will be really hard to find. I don't believe that Corsair even manufactures it in PC2100. I'm also wondering why exactly you feel the need for 2 GB of memory as it's going to cost you a fortune. 1 GB would be more than you will ever need. You can get 2 512 mb sticks and save yourself approximately $400 USD.
