Since you're using floats to position the LIs inside the custom pager, the containing UL counts as an empty block.
On my theme (zen-based), the stuff below it bumps up. On Garland it's not ideal either, as the top margin on the node links is getting eaten up.
Stick a class 'clear-block' on the UL so it contains its own floats.

I'm having this same problem with 6.x. The block below my custom pagers block is being overlapped by the previous and next links. Is there any way to remedy this on the theme level? I can't even seem to get the right class or ID to change anything in the custom pagers block. I have firebug but none of the class or ID names work.

Edit: I seemed to remedy this by adding a blank block with the code <div style="clear:both;"></div> below my custom pagers block. I couldn't find another way...
