It works, but it still introduces a ~4 second delay during the boot:

[    0.180847] usbcore: registered new device driver usb
[    0.181518] musb-omap2430 musb-omap2430: invalid resource
[    4.289093] twl 1-0048: PIH (irq 23) chaining IRQs 338..346
[    4.289276] twl 1-0048: power (irq 343) chaining IRQs 346..353
[    4.321228] twl4030_gpio twl4030_gpio: gpio (irq 338) chaining IRQs 354..371
[    4.446655] VUSB1V5: 1500 mV normal standby

Without these patches, it's:

[    0.186798] usbcore: registered new device driver usb
[    0.187438] musb-omap2430 musb-omap2430: invalid resource
[    0.213897] twl 1-0048: PIH (irq 23) chaining IRQs 338..346
[    0.214080] twl 1-0048: power (irq 343) chaining IRQs 346..353
[    0.215301] twl4030_gpio twl4030_gpio: gpio (irq 338) chaining IRQs 354..371
[    0.217926] VUSB1V5: 1500 mV normal standby

I'll try to find out what change is causing this.
