Wow, that didn't format correctly the first time.  Hopefully this time is 
better.

Here are all the documented and undocumented 'Dirty' parameters I know of.  
These go in the DIAGxx member of SYS1.PARMLIB.  
These are NOT recommended for production or even development environments.  
Try them on a TEST LPAR to shake out any problem areas.

Traps Name(IeaCmSetV, /* Ensure disabled CMSET caller */ 
IeaInitArSrb, /* Initialize registers for SRBs */ 
IeaInitRegsTask, /* Initialize registers for TCBs */
 IeaSpinLockV, /* Verify spin lock environment */ 
IeaScheduleV, /* Verify schedule environment */ 
IeaScheduleTrace, /* Trace SCHEDULE & IEAMSCHD */ 
IeaRpsgnlTrace, /* Trace RPSGNL calls */
/* Sloooow IgvCpoolGetV, /* Validate CPOOL GET environment */ 
IgvInitCpool, /* Initialize CPOOL GET elements */ 
IgvInitGetmain, /* Initialize GETMAINed storage */ 
IgvInitFreemain, /* Initialize FREEMAINed storage */ 
IarSt64InitGet, /* Initialize gotten 64-bit stg. */ 
IarSt64InitFree, /* Initialize freed 64-bit stg. */ 
IarCp64InitGet, /* Initialize gotten 64-bit cells */ 
IarCp64InitFree /* Initialize freed 64-bit cells */
)

Why does the option for "dirty" GETMAIN (I forget the correct name) remain 
undocumented, despite its value for testing?
