Considered being a consultant to software and or services firms that are IBM partners? You have a wealth of knowledge, know how IBM works, understand sales and marketing and have spare time on your hands. All things these companies need. Consultants helping these companies get started, position their products/services, make contacts, build a business plan to raise money, launch products/services, build their messaging etc will pay approx $1k-$2.5k per day short term and $800 to $1800 for mid/long term (1-3 months) for this kind of help. If they are really tight on cash flow, they will offer stock in lieu of hard cash for a portion of the daily rate.

Consider taking one of these jobs on a part time basis - 2-3 days per week. You might really enjoy it while avoiding the pressure of a 5 day a week gig.
