Hi Stellaman,
Your suggested methodology for changing the user ID and file ownership is the correct way to make the change. Bringing the User ID's and the Group ID's into alignment will probably be required, depending on what the user population is on the estate you may have to repeat this exercise for a number of users. Now would probably be a good time to plan a system for the management/alignment of the User ID's and Group ID's over the whole estate.
This is a common issue in the world of larger estates, it is frequently down to organic growth - where no or poor forward planning is in place. Large enterprises tend to have management tools in place, where user ID's can be correctly managed - this tends to happen after the problem has been encountered.

ddi_dma_devalign
ddi_dma_devalign(9F) Kernel Functions for Drivers ddi_dma_devalign(9F)
NAME
ddi_dma_devalign - find DMA mapping alignment and minimum transfer size
SYNOPSIS
#include <sys/conf.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int ddi_dma_devalign(ddi_dma_handle_t handle, uint_t *alignment, uint_t *minxfr);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
handle The DMA handle filled in by a successful call to ddi_dma_setup(9F).
alignment A pointer to an unsigned integer to be filled in with the minimum required alignment for DMA. The alignment is guaranteed
to be a power of two.
minxfr A pointer to an unsigned integer to be filled in with the minimum effective transfer size (see ddi_iomin(9F),
ddi_dma_lim_sparc(9S) and ddi_dma_lim_x86(9S)). This also is guaranteed to be a power of two.
DESCRIPTION
ddi_dma_devalign() determines after a successful DMA mapping (see ddi_dma_setup(9F)) the minimum required data alignment and minimum DMA
transfer size.
RETURN VALUES
ddi_dma_devalign() returns:
DDI_SUCCESS The alignment and minxfr values have been filled.
DDI_FAILURE The handle was illegal.
CONTEXT
ddi_dma_devalign() can be called from user or interrupt context.
