CM REST API Simpe Query results limitted to 50

I'm trying to use the CM REST API to return a collection of work items using the Simple Query resource. This is on a RTC 3.0.1.1 system. We have created a new work item type called PatchRequest with it's own category. We are also using the defect work item. When I run a simple query using the API on defects the results returned are what is expected. The oslc_cm.totalCount=1000 (which is the limit set on the CM application's advanced properties) and a total of 1000 items are returned in the resulting xml output. When I run a simple query using the API on PatchRequests only 50 items are returned out of a possible 1000. The oslc_cm.pageSize parm is being arbitrarily added to the collection request. this parm forces the limit of 50. This only happens when running the query on the PatchRequest work items, not on the defect work items. I have even tried adding my on oslc_cm.pageSize URL parm, but that is being ignored and replaced with a value of 50. I get this result from both the PERL program I use with CURL and also when I enter the simpleQuery url with the oslc_cm.query and oslc_cm.properties url parms.

Anyone have an idea of how I can lift the limitl of 50?
